“I have an excel file that cannot be opened for some reason. It says “the file might have been damaged or modified from its original format” Is there any way for me to recover the data from this file.”

“I have some RTF files that have become corrupted somehow and I need to find a way to recover them.”

File corruption can happen due to many reasons. Maybe you installed software and it turned out to be a bad one and infected and corrupted the files on your machine. Or maybe you did a conversion process and it corrupted your files. When things like that happen, the first thing you will want to know is how you can go about restoring corrupt files on your computer.

Fortunately, there are many ways to fix corrupted files, especially on Windows-based computers. Many tools have come into existence that allows you to fix and recover your corrupted files. The guide below shows the working and possible methods to repair and restore corrupted files on your Windows PCs.

Part 1. The Common Error Messages for Corrupted Files

Before you dive into the solutions, let’s first understand what a corrupted file error message looks like just to confirm you indeed have corrupted files on your machine. The following are some of the common messages your computer throws on your screen when you try to open a corrupted file.

  • The file is corrupt and cannot be opened.
  • The file or directory is corrupted and unreadable.
  • There was an error opening this document. The file is damaged.

If you are getting any one of the above errors on your computer, the following is what you need to recover corrupted files on your machine.

Part 2. How to Fix Corrupted Files in Windows 10/8/7?

While the methods mentioned below have worked for many of the users out there, you are recommended to keep trying all until you find the one that works for your situation. If one method fails, head to the next one, and so on.

Way 1. Change the File Format

Changing the format of your corrupted files often helps resolve the issue and makes your files usable again. You need to be sure to change the format to a suitable one though as converting an executable file to a Microsoft Word file will not work.

Let’s say your corrupted file is in the PNG format. What you can do is you can rename its extension from PNG to JPG and it should still work as both are image formats. You can then try opening the file in an image viewer on your computer and see if it works.

It usually works for image files but there is no harm trying it with other file types.

Way 2. Open the Corrupted File with Another Program

If you are having issues opening a file with certain software, you may try using another software to access the file. It could be the case that the software you are using has an issue and thus it is throwing off the corrupted message.

If you have a Microsoft Word file, for example, it can be opened using any other office suite including Google Docs as well. Try doing that and see if it helps fix the issue.

Way 3. Run SFC Scan

SFC stands for System File Checker and it is a utility that allows you to check and fix any broken files on your computer. You can use the utility to recover your corrupted files and the following is how you do it.

Step 1. Press the Windows + X key combo on your keyboard and select Command Prompt (Admin) to open a command prompt window with admin rights.

Step 2. When the window opens, type in the following command and hit Enter.

The tool will scan and fix any corrupted files on your Windows computer.

Way 4. Run DISK Check to Fix Bad Sector

If there is a bad sector on your disk, it could be causing your files to go corrupt. You can use the disk check utility on your Windows computer to fix such disk related issues.

The following is how to fix corrupted files using the disk check command-line utility:

Step 1. Press the Windows + X key and select Command Prompt (Admin) to open a command prompt window.

When the window opens, type in the following command and press Enter.

Step 2. It will scan and fix any issues on your disk.

Way 5. Recover Corrupted Files with Corrupted Files Recovery Software

If the above methods didn’t help you recover your files, then it’s time that you use a third-party data recovery software to get your lost files back on your Windows PC. Tenorshare 4DDiG for Windows Data Recovery is one of the data recovery software available in the market that lets you recover your data regardless of how you lost it on your computer.

How to scan for (and fix) corrupt system files in windows“Hi there, today when I connected USB drive on to my system, a window popped up asking me to Scan and Fix it. I followed it by clicking ‘Yes’ and performed the scan. Later, I found that many files from my USB drive are missing after Scan and Fix operation. I don’t even posses backup of those lost files, can anyone please suggest me how to recover files after scan and fix operation? Please help!!”

This kind of mishap is usually seen among various computer users, wherein users perform Scan and Fix on various storage devices and suffer loss of crucial files. Scanning of system drive is performed by running CHKDSK utility to mark and fix all bad sectors immediately. For external storage devices, the same is performed by right clicking on the device and selecting Scan option. But when CHKDSK is made to run, most of the times it erases all files from selected storage drive. So, before performing Scan and fix on any device, it is recommended to backup all files from it.

Scan and Fix is most frequently required in following scenarios:

  • When external storage devices are severely affected by virus/malware threats
  • Any damage to system drive due to file system corruption, header corruption, etc.
  • Incorrect way of formatting and reformatting the drive on any system can make it to show format error after which Scan and Fix is a must
  • When bad media spots gets piled on storage device making the memory space corrupt and inaccessible

In all above situations, user may perform Scan and fix on their storage devices or run CHKDSK on one’s computer to fix various issues and make the drive work properly. However, losing files after Scan and fix process is unavoidable. And if you are the one who have lost essential files from various storage devices after running Scan and Fix, then make use of reliable file recovery tool to bring back all your files.

Brilliant application to regain files after Scan and Fix:

The best utility to recover lost files after performing Scan and fix is Yodot File Recovery software. This tool can easily perform recovery of files like text, documents, excel sheets, presentations, notepad, Access files, OneNote, Outlook PST, etc. that are lost from system drives as well as external hard drives in numerous instances. Apart from this, the application can also bring back basic media file types from the storage devices formatted with FAT16, FAT32, ExFAT, NTFS and NTFS5 file systems. Addition to this, software can also bring back files from USB drives, FireWire drives, etc. that are lost due to accidental formatting, using unreliable antivirus to scan the device, etc. The software can be utilized on Windows computers running with Windows 10, Windows 8.1, Windows 8, Windows 7, Windows XP, Windows Vista, Windows 2003 and Windows 2008 operating systems. Apart from losing files on USB, pen drive or other external storage spaces, it happens sometimes that you end up deleting data present on it accidentally, when connected to computer. Later, you can’t find deleted files from USB in Recycle Bin as these data will be erased permanently. Even at those times you can utilize Yodot to restore your permanently deleted data.

Guidelines to get back lost files after scan and fix:

Note: If files are lost from external storage devices, then connect drive to a Windows computer and follow these steps.

  • Download Deleted files recovery software onto your Windows computer

Built inside of every version of Windows 10 is the System File Checker tool, a Swiss army knife of sorts that can help you navigate your way out of some of the trickiest jams you’ll face while using the operating system.

If a file has been modified, it’ll automatically replace that file with the correct version, thus saving you from the potential headache of having to troubleshoot the issue and replace the file yourself.

Here’s how it works.

  1. First we’re going to right click the Start button and select Command Prompt (Admin).

  • Once the Command Prompt appears, paste in the following: sfc /scannow
  • Leave the window open while it scans, which could take some time depending on your configuration and hardware. Once it’s done, you’ll see “Windows Resource Protection did not find any integrity violations.”
  • If it did find a problem, it’ll notify you with a message detailing what it is. Normally, it’ll attempt to fix the problem automatically by replacing the corrupted file with a new, correct version of it. If it doesn’t, we can try another baked-in Windows tool, called DISM, to fix it.

    1. Open the Command Prompt (Admin) again and copy in the following: DISM /Online /Cleanup-Image /RestoreHealth

    If this doesn’t work, you might have to consider a system restore to replace the corrupted file.

    How to scan for (and fix) corrupt system files in windows

    If your PC has been feeling buggy or having trouble during startup, it’s possible that Windows system files have become corrupt, gone missing, or even have been changed by a software installation somewhere along the line. Like most versions of Windows before it, Windows 10 includes a Command Prompt utility named Windows Resource Protection that will scan, verify, and fix system files.

    If your system is able to start, even in Safe Mode, you can run the utility right from Windows. If Windows won’t start, you can also run it from the Command Prompt available when you boot from your installation media into repair mode.

    To run this utility in Windows, you will need to open the Command Prompt in administrator mode. Right-click on the Start menu or press Windows+X on your keyboard, and choose “Command Prompt (Admin)” from the Administrative Tools menu. You can also just use this nifty keyboard shortcut.

    How to scan for (and fix) corrupt system files in windows

    When you have the Command Prompt open in administrator mode, you can run the utility by using the following syntax:

    The most useful option is just to scan the whole system immediately, which will scan and attempt to repair any files that are changed or corrupted. You can do that with this command:

    Alternatively, you can use the command sfc /verifyonly to scan for problems, but not perform any repairs.

    How to scan for (and fix) corrupt system files in windows

    You can also just scan or verify a particular file using the /scanfile= or /verifyfile= options along with the full path of the target file, like this:

    As we mentioned, this utility does exist for previous versions of Windows, but you may encounter slightly different options. You can always use the command sfc /? to get all supported options for your version of Windows. And just in case you’re wondering why Windows Resource Protection uses the command SFC, it’s because the utility used to be named System File Checker.

    How to scan for (and fix) corrupt system files in windows

    The System File Checker tool built into Windows can scan your Windows system files for corruption or any other changes. If a file has been modified, it will automatically replace that file with the correct version. Here’s how to use it.

    When You Should Run These Commands

    If Windows is experiencing blue-screen or other crashes, applications are failing, or some Windows features just aren’t working properly, there are two system tools that might be able to help.

    The System File Checker (SFC) tool built into Windows will scan your Windows system files for corruption or any other changes. If a file has been modified, it will automatically replace that file with the correct version. If the SFC command doesn’t work, you can also try the Deployment Image Servicing and Management (DISM) command on Windows 8, 10, or 11 to repair the underlying Windows system image. On Windows 7 and earlier, Microsoft offers a downloadable “System Update Readiness Tool” instead. Let’s take a look at how to use them.

    Run the SFC Command to Repair System Files

    Run the SFC command when troubleshooting a buggy Windows system. SFC works by scanning for and replacing system files that are corrupt, missing, or changed. Even if the SFC command doesn’t repair any files, running it will at least confirm that no system files are corrupted and then you can continue to troubleshoot your system with other methods. You can use the SFC command as long as the computer itself will start. If Windows will start normally, you can run it from an administrative command prompt. If Windows won’t start normally, you can try starting it in Safe Mode or in the recovery environment by booting from your installation media or recovery disc.

    However you get to the Command Prompt — normally, Safe Mode, or recovery environment — you’ll use the command the same way. Just remember that if you start Windows normally, you will need to open the Command Prompt or PowerShell with administrative privileges. To do this, right-click the Start button and select “Command Prompt (Admin)”.

    Note: On Windows 11, you might need to select “Windows Terminal (Admin)” instead of “Command Prompt (Admin)” or “PowerShell (Admin)”.

    How to scan for (and fix) corrupt system files in windows

    At the Command Prompt, type the following command and press Enter to run a full system scan and have SFC attempt repairs:

    How to scan for (and fix) corrupt system files in windows

    Leave the Command Prompt window open until the command completes, which may take some time. If everything is fine, you’ll see the message “Windows Resource Protection did not find any integrity violations.”

    If you see a “Windows Resource Protection found corrupt files but was unable to fix some of them” message, try restarting your PC in Safe Mode and running the command again. And if that fails, you can also try booting with your installation media or recovery disc and trying the command from there.

    How to scan for (and fix) corrupt system files in windows

    Run the DISM Command to Fix SFC Problems

    You shouldn’t normally have to run the DISM command. However, if the SFC command fails to run properly or can’t replace a corrupted file with the correct one, the DISM command — or System Update Readiness Tool in Windows 7 — can sometimes fix the underlying Windows system and make SFC run correctly.

    To run the DISM command in Windows 8, 10, and 11, open Command Prompt, PowerShell, or Windows Terminal with administrative privileges. Type the following command and then press Enter to have DISM check your Windows component store for corruption and automatically fix any problems it finds.

    Allow the command to finish running before closing the Command Prompt window. This may take five to ten minutes. It’s normal for the progress bar to stay at 20 percent for a while, so don’t worry about that.

    How to scan for (and fix) corrupt system files in windows

    If the results of the DISM command state that anything was changed, restart your PC and you should then be able to run the SFC command successfully.

    On Windows 7 and earlier, the DISM command isn’t available. Instead, you can download and run the System Update Readiness Tool from Microsoft and use it to scan your system for problems and attempt to fix them.

    Note: If you’re still using Windows 7, you’ll need to grab the right version of the Readiness Tool. The latest version available is “System Update Readiness Tool for Windows 7 for x64-based Systems (KB947821) [October 2014].” Download that one.

    Try a System Restore or System Reset Next

    If you’re still experiencing system problems and the SFC and DISM commands don’t help, you can try more drastic actions.

    Running the System Restore tool will restore your Windows operating system files, settings, and applications to an earlier state. This may fix system corruption problems if the operating system wasn’t also damaged at the earlier point when the restore point was created.

    An if all else fails, you could always resort to performing a system reset or reinstalling Windows. On Windows 8, 10, and 11 you can perform a “Reset this PC” operation to reset Windows to its default state. You’ll have the option to keep your personal files in place — though you’ll have to reinstall programs — or to remove everything and do a complete reinstall. Whichever you choose, make sure you’ve backed up your PC first! On Windows 7 and earlier, this will require using your computer’s manufacturer-provided recovery partition or reinstalling Windows from scratch.

    How to scan for (and fix) corrupt system files in windows

    If you encounter other errors while running any of the commands we’ve covered, try searching the web for the specific errors you encounter. The commands will often point you to log files with more information if they fail — check the logs for more details about specific problems. Ultimately, it may not be worth troubleshooting serious Windows corruption problems when you can just reset Windows to its default state or reinstall it. That decision will be up to you.

    How to scan for (and fix) corrupt system files in windows

    If your Windows system is acting weird or is unbearably slow, the first thing you need to do is scan and remove any viruses or malware. Apart from that, the other reason might be the corrupted system files. There are a variety of reasons why system files get corrupted, like a sudden power failure, system crash, errors while updating, version mismatch, etc. No matter what the reason is, if you ever think your system is slow or the system files hvee been corrupted, here is how you can scan and fix corrupted Windows files using the DISM (Deployment Image Servicing and Management) command line tool.

    Note: I’m using Windows PowerShell to scan and fix the problems. However, you can also use the Command Prompt with the same exact commands and procedures discussed below.

    Scan for Corrupted Windows System Files

    To start, search for PowerShell in the Start menu. Right-click on it, and then select the option “Run as administrator.” This action will open the Windows PowerShell.

    How to scan for (and fix) corrupt system files in windows

    In the PowerShell window copy and paste the below command. This command invokes the Windows Resource Protection to check for any file corruptions or violations. The scan may take some time to complete, so sit back and wait for the results.

    Once the scan is completed, it will display a message something like what is show below if there are any problems. Windows tries to fix them by itself, but more often than not it fails to do so. Continue on to the next step.

    How to scan for (and fix) corrupt system files in windows

    Fix Corrupted Windows System Files

    If the SFC command didn’t fix the problem, then we can use the DISM tool with RestoreHealth and Source switches. To start, copy the below command, and execute it in the PowerShell.

    As soon as you execute the command, Windows starts the process of fixing it. While fixing it, the progress bar may get stuck at 20%. This is normal. Just wait for a while for the process to continue. If the command fixes the problem then that’s good. If not, continue on. In my case Windows failed to fix the problem. If you want to know what the actual error is, open the DISM log from the location displayed in the Powershell.

    Now, we are going to use the /Source switch where we point the DISM tool toward the Windows installation media so that it can fix the problem using the source files. Insert your installation media, be it a DVD or USB driver. If you don’t have the installation drive, download the latest Windows ISO from Microsoft and mount it (right-click on ISO and select the option “Mount”).

    Once you’ve done that, execute any one of the below commands. Don’t forget to replace “X” with the actual drive letter of your Windows installation media.

    The second command prevents DISM from using Windows Update for online images. If everything goes well, you will see a message reading “restoration operation completed.” Just like before, it may take some time to complete the procedure.

    Now, again use the SFC command so that Windows can fix any minor problems.

    When the procedure has been completed, you will see a message like the one below.

    How to scan for (and fix) corrupt system files in windows

    If you scan again with the sfc command, you should see a message like the one below. This confirms that there are no more file corruptions or violations.

    How to scan for (and fix) corrupt system files in windows

    Windows System Files can get corrupted due to many reasons such as incomplete Windows Update, improper shutdown, virus or malware, etc. Also, a system crash or a bad sector on your hard disk can lead to corrupted files, which is very it is always recommended to back up your data.

    In case, if any one of your files gets corrupted then it becomes hard to recreate that file or even fix it. But don’t worry there is a built-in Windows tool called System File Checker (SFC) which can act like a swiss knife and can fix corrupted or damaged system files. Many programs or third-party apps can make certain changes to the system files and once you run the SFC tool, these changes are automatically restored. So without wasting any time let’s see how to repair corrupted system files in Windows 10 with the help of the below-listed tutorial.

    How to scan for (and fix) corrupt system files in windows

    Now sometimes the System File Checker (SFC) command does not work well, in such cases, you can still repair the corrupted files using another tool called Deployment Image Servicing & Management (DISM). The DISM command is essential for repairing the fundamental Windows system files which are required for the proper functioning of the operating system. For Windows 7 or earlier versions, Microsoft has downloadable “System Update Readiness Tool” as an alternative.

    How to Repair Corrupted System Files in Windows 10

    Make sure to create a restore point just in case something goes wrong.

    Method 1: Run SFC Command

    You can run the System File Checker before doing any complex troubleshooting such as the clean installation of the operating system, etc. SFC scan & replace the corrupted system files and even if the SFC is unable to repair these files, it will confirm that whether or not the system files are actually damaged or corrupted. And in most cases, the SFC command is enough to fix the issue and repair the corrupted system files.

    1.The SCF command can be only used if your system can start normally.

    2.If you are unable to boot to windows, then you need to first boot your PC into safe mode.

    3.Press Windows Key + X then click on Command Prompt(Admin).

    How to scan for (and fix) corrupt system files in windows

    4.Now type the following in the cmd and hit enter:

    5.Wait for the above process to finish and once done restart your PC.

    7.Let the above process complete and again reboot your PC to save changes.

    Method 2: Run DISM Command

    DISM (Deployment Image Servicing and Management) is a command-line tool that users or administrators can use to mount and service a Windows desktop image. With the use of DISM users can alter or update Windows features, packages, drivers, etc. DISM is a part of Windows ADK (Windows Assessment and Deployment Kit) which can be easily downloaded from the Microsoft website.

    Normally, the DISM command is not required but if the SFC commands fails to fix the issue then you need to run the DISM command.

    1.Press Windows Key + X then select Command Prompt (Admin).

    How to scan for (and fix) corrupt system files in windows

    2.Type DISM /Online /Cleanup-Image /RestoreHealth and press enter to run DISM.

    A system crash or bad sectors in the hard drive can lead to corrupted files, which is why it’s crucial to always back up your data. If one of your important files gets corrupted, then sadly it’s very difficult to fix it. You simply can’t recreate data that isn’t even there.

    However, there is a slight chance you may be able to fix a file if it’s a minor issue or less data got corrupted. Surely that slight chance is more than enough for you if the file is important. And to help you with that, the following are a few ways to fix damaged or corrupted files in Windows.

    Change the file format

    Changing a file’s format can sometimes help fix it. The file may not be able to open in its original form, but you should at least be able to access the file contents. For example, you can convert Microsoft Word documents to PDF format, or images in PNG format to JPG.

    How to scan for (and fix) corrupt system files in windows

    There are free online converters available for almost every file type. Just search online for “convert (your file format) to (the file format you want to convert to).” You should be able to get a good online converter to convert your file for free. Below are some popular online file converters to start with:

    Use a different program

    A single file format can be opened by many programs, both built-in and third-party. Additionally, each program has its own algorithm and requirements for opening a file. Your current program might not be able to open the file, but an alternative program may be able to open it. For example, a Word document can also be opened by alternative programs like LibreOffice and even Google Docs.

    How to scan for (and fix) corrupt system files in windows

    You should also try to look for a more comprehensive program to open the file. For example, to open a corrupted video file, try using VLC media player instead of Windows’ built-in player.

    Once you have the alternative program, right-click on the file and hover your mouse cursor over the “Open with” option. The alternative program should be here. If not, then click on “Choose default program” to open all the installed applications.

    A system crash or bad sectors in the hard drive can lead to corrupted files, which is why it’s crucial to always back up your data. If one of your important files gets corrupted, then sadly it’s very difficult to fix it. You simply can’t recreate data that isn’t even there.

    However, there is a slight chance you may be able to fix a file if it’s a minor issue or less data got corrupted. Surely that slight chance is more than enough for you if the file is important. And to help you with that, the following are a few ways to fix damaged or corrupted files in Windows.

    Change the file format

    Changing a file’s format can sometimes help fix it. The file may not be able to open in its original form, but you should at least be able to access the file contents. For example, you can convert Microsoft Word documents to PDF format, or images in PNG format to JPG.

    How to scan for (and fix) corrupt system files in windows

    There are free online converters available for almost every file type. Just search online for “convert (your file format) to (the file format you want to convert to).” You should be able to get a good online converter to convert your file for free. Below are some popular online file converters to start with:

    Use a different program

    A single file format can be opened by many programs, both built-in and third-party. Additionally, each program has its own algorithm and requirements for opening a file. Your current program might not be able to open the file, but an alternative program may be able to open it. For example, a Word document can also be opened by alternative programs like LibreOffice and even Google Docs.

    How to scan for (and fix) corrupt system files in windows

    You should also try to look for a more comprehensive program to open the file. For example, to open a corrupted video file, try using VLC media player instead of Windows’ built-in player.

    Once you have the alternative program, right-click on the file and hover your mouse cursor over the “Open with” option. The alternative program should be here. If not, then click on “Choose default program” to open all the installed applications.

    Run SFC scan

    SFC scan helps look for corrupted system files and fixes them automatically. If a particular system file is preventing your file from opening, or the file itself is a system file, then running SFC scan should fix it.

    Press the Win + R keys and type cmd in the Run dialog to open Command Prompt. Type sfc /scannow and hit Enter. The scan will start and will take five to fifteen minutes to complete.

    With each passing day, the challenges for cybersecurity experts are increasing as the attack on users’ networks and computers are not limited to malware, worm, or Trojan, etc. There are spyware and ransomware that can destroy your computer and make it unusable. It is hard to recognize a virus file as they are standard programs that execute on your machine, but with malicious intent. For example, a hacker may put spyware that runs in a stealth manner and provides access to a hacker inside your computer or network.

    The symptoms of any corruption in Windows is recognized by the abnormal behavior of computer files or account-

    1. The computer crashes abruptly after showing a blue screen error.
    2. The computer runs out of memory even when few programs are running.
    3. Many programs become too slow to open and execute that was working fine until recently.
    4. Some unknown programs start to run automatically during the boot process.
    5. Your account refuses your correct password or changes it without giving any warning.

    Windows 10 has accumulated all the possible threats that can occur in the system and crash it beyond repair. So, you should use several security features that will protect you from attacks in advance.

    Windows Defender Smart Screen

    The Windows Defender Smart Screen stops the threat at first sight. It forbids the users from opening a website that is termed ‘malicious’ or stops such downloads that do not clear its filter criteria. It fights against scamming sites, phishing, fake ads, and drive-by attacks.

    User Account Control

    User Account Control makes the management of the whole computer much better by running all the applications and tasks under a security context. It checks that which application is authorized by the user and which is not. So, malware or spyware will not even start and corrupt the stem. Although, the administrator can check the filter and allow safe-looking and healthy processes. It reduces the chances of accidental changes to a minimum.

    Windows Defender Application Guard

    Windows Defender Application Guard provides security to Microsoft Edge Web Browser. It uses Hyper-V Virtualization technology to whitelist the site and show them as trusted sites. When the site is not trusted, then Application Guard opens it in a secure container excluding access to memory, store, endpoints, and other applications.

    Microsoft Bitlocker

    It is a full-end encryption solution provided to Professionals and business enterprises. It expands the file and system protection and makes the data inaccessible when the computer is decommissioned.

    Windows Defender Credential Guard

    Defender Credential Guard provides software access to only privileged users. It uses virtualization-based security to assess the rightful users who are authorized by the administrator to run some programs. For example, in a shared computer, the administrator can block some users from running Exchange Server.

    If you are not using any of the above-mentioned security features, then your computer may face corruption, and many files may become affected by it. If you are also facing such corruption, then use the following methods to repair the affected file or sector.

    Run sfc scan

    System File Checker (sfc) is the inbuilt utility feature that checks the system file for supposed corruption and shows you the affected area. If you can run it in the command prompt as an Administrator.

    and click Enter.

    The process will take some time to complete and show any errors in the system file.

    Run SFC in safe mode

    If the sfc scan does not complete the process or show the correct problem, then you can try to run in safe mode.

    1. Restart the computer and go to the Troubleshoot mode.
    2. Click Advanced options, then Startup Settings, and choose to restart.
    3. Choose the safe mode to boot the computer and run the command prompt as the Administrator.
    4. Type sfc /scannow option.
    Restore Windows 10

    The System Restore is an inbuilt service that helps you to restore Windows to a previous state leaving the changes committed after it. In the restore feature, you choose a time that works as the restoration point. If you suspect that corruption in Windows is new, then you can restore it to a select point. Here is how you can create it-

    1. Type restore point in the search bar and click it.

    Windows 10 comes with built-in tools to check and repair the System Files on your computer. You will find below the steps to Repair System Files using SFC and DISM tools in Windows 10.

    How to scan for (and fix) corrupt system files in windows

    Repair Windows System Files Using SFC

    Windows System File Checker (SFC) tool can be used to check the System Files for errors or corruption and fix them.

    SFC basically scans the integrity of system files on your computer and automatically replaces them with correct version files, in case they are found to be missing, corrupted, damaged or changed.

    You can use the SFC tool, if your computer is crashing, generating error messages and going through problems.

    Steps to Repair Windows System Files Using SFC

    Follow the steps below to run SFC command to repair corrupted or damaged Windows System Files.

    1. Right Click on the Start button and select Command Prompt (Admin) .

    2. On the Command Prompt window, type sfc /scannow and press the Enter Key on the keyboard of your computer.

    How to scan for (and fix) corrupt system files in windows

    Note: There should be a space after sfc.

    3. Patiently wait for Windows 10 to scan your computer for System File Errors and fix them.

    It may take anywhere from 10 to 20 minutes for the full system scan to be completed. Once the SFC scan is completed it will come up with one of the following results.

    • Windows Resource Protection did not find any integrity violations (which is a good result)
    • Windows Resource Protection found corrupt files and repaired them (better than good!)
    • Windows Resource Protection found corrupt files but was unable to fix some (or all) of them (not a good result)

    In case you get the third message, you need to take the help of DISM tool to fix the problem.

    Repair Windows System Files Using DISM

    Microsoft defines DISM (Deployment Image Servicing and Management) as a command-line tool that combines separate Windows platform technologies into a single, cohesive tool for servicing Windows images.

    DISM is generally used when the System File Checker (SFC) is unable to fix problems on a computer.

    DISM tool has the capability to fix Component Store Corruption that is known to prevent SFC Scan from functioning properly on a computer.

    Steps to Repair System Files Using DISM

    1. Right-click on the Start button and click on Command Prompt(admin) .

    2. On the command prompt window, type DISM /Online /Cleanup-Image /RestoreHealth and press the Enter Key .

    How to scan for (and fix) corrupt system files in windows

    Note: There needs to be a space after DISM, Online and Cleanup-Image.

    3. Wait for the DISM tool to check your computer for errors and fix them.

    The DISM process may take anywhere from 10 to 15 minutes or more. Also, the progress bar may not show up for a while and you may find the progress stuck at 20 percent for a long time.

    After the DISM command has finished running, restart your computer and run the SFC command once again to replace remaining corrupted files (if any) with the correct ones.

    How to scan for (and fix) corrupt system files in windows

    The System File Checker tool built into Windows can scan your Windows system files for corruption or any other changes. If a file has been modified, it will automatically replace that file with the correct version. Here’s how to use it.

    When You Should Run These Commands

    If Windows is experiencing blue-screen or other crashes, applications are failing, or some Windows features just aren’t working properly, there are two system tools that might be able to help.

    The System File Checker (SFC) tool built into Windows will scan your Windows system files for corruption or any other changes. If a file has been modified, it will automatically replace that file with the correct version. If the SFC command doesn’t work, you can also try the Deployment Image Servicing and Management (DISM) command on Windows 8, 10, or 11 to repair the underlying Windows system image. On Windows 7 and earlier, Microsoft offers a downloadable “System Update Readiness Tool” instead. Let’s take a look at how to use them.

    Run the SFC Command to Repair System Files

    Run the SFC command when troubleshooting a buggy Windows system. SFC works by scanning for and replacing system files that are corrupt, missing, or changed. Even if the SFC command doesn’t repair any files, running it will at least confirm that no system files are corrupted and then you can continue to troubleshoot your system with other methods. You can use the SFC command as long as the computer itself will start. If Windows will start normally, you can run it from an administrative command prompt. If Windows won’t start normally, you can try starting it in Safe Mode or in the recovery environment by booting from your installation media or recovery disc.

    However you get to the Command Prompt — normally, Safe Mode, or recovery environment — you’ll use the command the same way. Just remember that if you start Windows normally, you will need to open the Command Prompt or PowerShell with administrative privileges. To do this, right-click the Start button and select “Command Prompt (Admin)”.

    Note: On Windows 11, you might need to select “Windows Terminal (Admin)” instead of “Command Prompt (Admin)” or “PowerShell (Admin)”.

    At the Command Prompt, type the following command and press Enter to run a full system scan and have SFC attempt repairs:

    Leave the Command Prompt window open until the command completes, which may take some time. If everything is fine, you’ll see the message “Windows Resource Protection did not find any integrity violations.”

    If you see a “Windows Resource Protection found corrupt files but was unable to fix some of them” message, try restarting your PC in Safe Mode and running the command again. And if that fails, you can also try booting with your installation media or recovery disc and trying the command from there.

    Run the DISM Command to Fix SFC Problems

    You shouldn’t normally have to run the DISM command. However, if the SFC command fails to run properly or can’t replace a corrupted file with the correct one, the DISM command — or System Update Readiness Tool in Windows 7 — can sometimes fix the underlying Windows system and make SFC run correctly.

    To run the DISM command in Windows 8, 10, and 11, open Command Prompt, PowerShell, or Windows Terminal with administrative privileges. Type the following command and then press Enter to have DISM check your Windows component store for corruption and automatically fix any problems it finds.

    Allow the command to finish running before closing the Command Prompt window. This may take five to ten minutes. It’s normal for the progress bar to stay at 20 percent for a while, so don’t worry about that.

    How to scan for (and fix) corrupt system files in windows

    If the results of the DISM command state that anything was changed, restart your PC and you should then be able to run the SFC command successfully.

    On Windows 7 and earlier, the DISM command isn’t available. Instead, you can download and run the System Update Readiness Tool from Microsoft and use it to scan your system for problems and attempt to fix them.

    Note: If you’re still using Windows 7, you’ll need to grab the right version of the Readiness Tool. The latest version available is “System Update Readiness Tool for Windows 7 for x64-based Systems (KB947821) [October 2014].” Download that one.

    Try a System Restore or System Reset Next

    If you’re still experiencing system problems and the SFC and DISM commands don’t help, you can try more drastic actions.

    Running the System Restore tool will restore your Windows operating system files, settings, and applications to an earlier state. This may fix system corruption problems if the operating system wasn’t also damaged at the earlier point when the restore point was created.

    An if all else fails, you could always resort to performing a system reset or reinstalling Windows. On Windows 8, 10, and 11 you can perform a “Reset this PC” operation to reset Windows to its default state. You’ll have the option to keep your personal files in place — though you’ll have to reinstall programs — or to remove everything and do a complete reinstall. Whichever you choose, make sure you’ve backed up your PC first! On Windows 7 and earlier, this will require using your computer’s manufacturer-provided recovery partition or reinstalling Windows from scratch.

    How to scan for (and fix) corrupt system files in windows

    If you encounter other errors while running any of the commands we’ve covered, try searching the web for the specific errors you encounter. The commands will often point you to log files with more information if they fail — check the logs for more details about specific problems. Ultimately, it may not be worth troubleshooting serious Windows corruption problems when you can just reset Windows to its default state or reinstall it. That decision will be up to you.

    By Nathan E. Malpass, Last updated: July 27, 2020

    Bad sectors located within your hard drive results in corrupted files. The same goes for system crashes. That’s why it’s very important to back your data up all the time. If a precious file gets corrupted, fixing it becomes complicated and difficult.

    Fortunately, there’s still a possibility of fixing a file if the issue is minor. This is also true if only a few data became corrupted. This small chance of fixing corrupted data is very important especially if the files are precious.

    In this guide, we’ll teach you how to fix corrupted files (including damaged ones) within the Windows operating system. Read on to learn more.

    Part 1. An Overview of Data Corruption

    Let’s say there’s a hospital that has various filing cabinets where patient information is stored. Each patient has his/ her own folder containing their medical records and personal information. Every folder that pertaining to each patient has a particular place within the filing cabinet depending on different categories that divide them.

    Now, the hospital is very busy. The filing cabinets and its drawers are continuously opened and closed. Patient folders are, also, continuously extracted and placed back into its respective locations. You might be thinking that because of too much work and a massive amount of patient folders, data can actually be scrambled. Thus, it is necessary to know how to fix corrupted files at this point.

    Some of the defects include, but are not limited to, the following:

    • As hospital staff takes and puts back folders, papers inside it are not placed in order. Sometimes, they are damaged and the worst case is the papers can be lost.
    • Doctors might put incorrect information on prescription forms. Incorrect data can also be placed in a specific folder.
    • Transferring files from one place to another might lead to papers being lost inside their respective folders.
    • Natural disasters and vandals can ultimately ruin most of the folders. Or worse, it could lead to the corruption or damage of all of the filing cabinets.
    • A particular drawer might have a jam. In this case, patient records from A to C, for example, cannot be accessed.
    • Patient XYZ can have the same name as another patient. Their medical records can be interchanged. Thus, Patient XYZ’s can have both his records and the information of another person.

    Your hard drive is definitely not a filing cabinet. However, when it puts information into storage, it has the same mechanisms. Data are stored as demagnetized and magnetized areas. These are represented by 0 and 1, respectively.

    Part 2. Corrupted Files: What Are They?

    Before we delve into how to fix corrupted files, let us define what they are first. Corrupted files are like damaged folders (as stated above). When data is scrambled, lost, or damaged, the file becomes unreadable. Thus, digital corruption happens when the data within a particular file are scrambled. The 0s and 1s that compose the file are messy and results in the destruction of the file’s integrity.

    Part 3. Top Ways on How to Fix Corrupted Files

    Solution 01. Using Data Recovery Tools

    The best solution wouldn’t refer to addressing the problem directly. It pertains to recovering the data of damaged files so it isn’t lost. For this, we recommend that you use FoneDog Data Recovery software.

    Solution 02. Modify File Format

    Sometimes, you have to change the format of the file in order to solve the problem on how to fix corrupted files. With this method, you won’t have access to the original format of the file. However, you may still access some of the contents of the corrupted data.

    For instance, DOCX documents can be converted to PDF files. JPG images can also be converted to PNG. These can be done by using free online converters you can search for with Google. Most of them are free and you don’t have to pay anything to convert your files from one format to another.

    Solution 03. Using Another Program

    One file format is usually capable of being opened by different types of programs. For instance, your DOCX Microsoft Word file can be opened by Google Docs and even WPSOffice. For video files that are corrupted, you might try VLC Media Player. Use this in place of the built-in Windows Media Player. To open your file using another program, simply right-click on the file. Then, place your mouse cursor over “Open With” and then select another program from the list.

    Solution 04. Running SFC Scan

    When you want to know how to fix corrupted files, then the SFC scan is the way to go. It scans your system for corrupted files and fixes the damaged data. Here are the steps on how to do it:

    • Step 01 – Press the keys for Windows + R. Type CMD within the search bar and launch Command Prompt.
    • Step 02 – Type out “sfc /scannow” and then press Enter.
    • Step 03 – Wait until the scan is complete.

    Solution 05. Using Third-Party File Repair Software

    When it comes to fixing your corrupted files, the last resort would be to use a third-party file repair tool. Usually, these tools are purchased and comes with a free trial allowing you to repair files partially.

    These tools can also tell you whether a file can be repaired or if it’s a lost cause. Different file repair software can fix different file types. For instance, one tool can repair images and another one can repair ZIP files.

    Part 4. To Wrap It All up

    Various solutions can be done in order to implement how to fix corrupted files. We’ve shown you different ways on how to do so. The best troubleshoot would be to use FoneDog Data Recovery in order to recover your corrupted files.

    Corrupted files can occur on any file type, including Word, Excel, PDF, image files, and Windows system files. When this occurs, you’ll see an error that says something like, “The file is corrupt and cannot be opened,” or “The file or directory is corrupted and unreadable.” Another message that you’ll see is, “Word found unreadable content in [filename]. Do you want to recover the contents of this document?”

    These errors occur when you double-click the file to open it, or when you attempt to open it from within an application. If you encounter one of these messages, here are some ways to fix the problem.

    These fixes apply to all editions of Windows 10, Windows 8, and Windows 7, including 32-bit and 64-bit versions.

    How to scan for (and fix) corrupt system files in windows

    Causes of Corrupted Files

    There are a number of reasons files can get corrupted. One common reason is that the sector on the hard disk where the file is stored had physical damage. A sector with physical damage is known as a bad sector.

    In other cases, multiple files are allocated to the same space in memory, triggering a corrupted file error. Files are stored in memory in a cluster, and sometimes a bug in the operating system, or a computer crash, may lead to two files getting assigned to the same cluster.

    Viruses that erroneously mark hard drive sectors as bad can also lead to files getting corrupted.

    How to Fix Corrupted Files

    Corrupt file errors can be unpredictable and can happen when least expected. A corrupt file can be repaired only about half the time. Try these fixes to see if you can get to the bottom of your corrupt file error.

    Perform a check disk on the hard drive. Running this tool scans the hard drive and attempts to recover bad sectors. After the sectors are repaired, reopen your file again to see if it’s no longer corrupted.

    Use the CHKDSK command. This is the command version of the tool we looked at above. It’s worth a try if the check disk tool failed.

    Use the SFC /scannow command. This command aims to find and repair corrupt Windows system files.

    Change the file format. Use a free file converter app, or open the file with any application that automatically converts from other file formats. For example, open a corrupted Word document with a PDF app to launch a file-conversion utility. Often, a file conversion alone repairs a corrupt file.

    Use file repair software. If you’re desperate to fix the file and recover your information, try a file repair utility. There are both free and paid tools, such as Hetman, Repair Toolbox, or FileRepair. Try Digital Video Repair for corrupt video files, Zip Repair for corrupt ZIP files, or OfficeFIX to repair Microsoft Office files.

    Protect Files From Corruption

    Since file corruption can happen on any file and for many reasons, it’s important to make regular backups of your files. Use backup software to keep your important files backed up at all times. This way, if a file is corrupted, you can recover it from the backup.

    A corrupted file could be a symptom of a virus, but it isn’t a virus itself. To determine whether a virus might be causing the problem, run one of the best antivirus software programs.

    Power outages can corrupt files, so adding a battery-powered uninterrupted power supply (UPS) to your home or office setup protects your hardware from damage and files from corruption. Team this strategy with a top-notch backup service where you can retrieve any file that is corrupted, and you can usually avoid corrupted files.

    How to scan for (and fix) corrupt system files in windows

    Ever been power typing on your keyboard with 100 tabs up on google, trying to get a really important piece of work finished and this horrific blue screen pops up? The immediate reaction for many is ‘why on earth did I not save that file’ or ‘please please please can this not be due to a corrupt file.’ If it is the latter, we know how you feel and are here to tell you how to fix it.

    Windows, aware of this problem, have built a System File Checker in their latest update of Windows 10. This checker scans your system files, alerting you where there is corruption or any other changes. Windows will then go on to replace any files that have been modified or corrupted with the correct and original version of this file. If, however, the System File Checker fails to replace your file there is a second option. This option is the DISM command. DISM stands for Deployment Image and Servicing management. This Windows tool fixes the component corruption which prevents the System File Checker from working properly.

    When should I use these options?

    Use the System File Checker or DISM when;

    • The Windows blue screen (as shown above) is displayed
    • Applications are crashing
    • Certain Windows applications aren’t working correctly.

    To see how to fix this issue, either watch the video or read the instructions below:

    What option should I use first?

    Use the System File Checker command first as it will solve the most common problems. However, if it does not fix the problem it will then eliminate the possibility of your system files being corrupted and will allow you to use other methods.

    If that doesn’t work the second option should always be the DISM command. The DISM option is second as these problems are less common. However, problems associated with the System File Checker are also associated with DISM. So if they can’t be fixed by the File Checker it is likely that the DISM can fix the underlying system, allowing the checker to then run correctly.

    Okay, Great. But how do I run the System File Checker!?

    To start the process, you will need to be in the Administrator Command Prompt window. To do this, right-click on the Windows/Start button in the bottom left corner of your screen. Then click Command Prompt (Admin).’

    How to scan for (and fix) corrupt system files in windows

    Then type in sfc/scannow and press Enter to run the application. This needs to be left for around 5-10 minutes to run correctly and outline any issues. If there are no issues the message ‘Windows Resource Protection did not find any integrity violations’ will appear.

    How to scan for (and fix) corrupt system files in windows

    However, if the message Windows Resource Protection found corrupt files but was unable to fix some of them’ then the application has found the issue. This means that your computer or laptop needs to be rebooted in safe mode. To do this hold the shift key while clicking the restart option– this will give you the advanced boot options menu. Once the computer has restarted, repeat the steps above to run the System File Checker and the first message should appear stating that no ‘integrity violations’ were found.

    If this doesn’t work it is time to use the DISM Command

    Open the Command Prompt (Administrator) window as seen above. But instead of typing in sfc/scannow’ type in ‘DISM /Online /Cleanup-Image /RestoreHealth’

    How to scan for (and fix) corrupt system files in windows

    Again, this will take 5-10 minutes. The progress bar initially may be slow, but do not cancel the command. A message will then appear outlining if a change has been made. If a change has been made, restart your computer and run the System File Checker command and hopefully it should now replace any corrupt files.

    System Restore/Reset

    If all the steps above haven’t helped running the system restore tool will restore your operating system files to a previous state, a time where the files were not corrupt.

    To do this click on the Start/Windows button in the bottom left of the screen. Type in System Restore in the search bar and click create a restore point.’ Then in the system properties pop up click on the System Restore button. Enable the turn on the system protection’ button and move the Max Usage slider to around 5-10%. This will determine how much of your hard drive to use in restoring. Then press apply.

    Alternatively, you can reset your system or reinstall Windows. This will remove apps and settings, but keep your personal files if you wish. To do this you click on Settings > Update & Security > Recovery (left pane) > Get Started. You then have to decide whether you want to ‘Keep My Files’ or ‘Remove Everything’ depending on whether you want to keep your data files on your computer.

    How to scan for (and fix) corrupt system files in windows

    Remove everything will take a longer time and if you then click ‘Remove files and clean the drive’ it will make recovering removed files a lot harder. (This is good when you are selling or giving away your computer). Then click Next > Reset > Continue. This should reset Windows back to its basic state and remove any corruption.

    I n this tutorial, we are going to see how to fix corrupted files in Windows 10. Some Windows functions do not work properly anymore or Windows crashes without warning? Then the System File Checker (SFC) tool can help you! This tool allows you to analyze the Windows system files and repair the missing or damaged ones, and thus get Windows back to work. This will probably allow you to avoid a Windows repair that can take quite some time.

    What is the System File Checker (SFC)?

    The SFC is a tool that runs on the command line. Once executed, it will perform an analysis of system files that may be corrupted or damaged. Once found, the tool will then attempt to repair the damaged files. If the tool succeeds in repairing them, the user will not be forced to reinstall the entire operating system.

    How to Fix Corrupted Files in Windows 10

    Depending on your version of Windows, you can choose to run the SFC tool either in PowerShell or in Command Prompt (in administrator mode). In this example, We are going to use the Windows 10 PowerShell.

    Step 1: To check this, type PowerShell in the Windows search bar. Then right-click on Windows PowerShell and Run as administrator.

    Step 2: In the PowerShell window, type the following command, then press Enter:

    Do not close the PowerShell window until the check is complete. The scan results will be displayed after this process is complete.

    When the process is complete, one of the following messages may appear:

    • Windows Resource Protection did not find any integrity violations. This means that no system files are missing or damaged.
    • Windows Resource Protection found damaged files and was able to repair them. Details are provided in the log CBS.Log %WinDir%\Logs\CBS\CBS.log.

    In case your version of Windows is corrupted in such a way that booting the operating system is impossible, you still have other methods to run the system file checker.

    The first method is to start Windows in Safe Mode and from there launch the command prompt.

    The second method is to run the system file checker using another Windows machine. To do this, you need to connect the hard disk with the corrupted version of Windows to another working Windows machine.

    Windows system files are the core files without the presence of which the operating system cannot be brought in a functional state. However, at times due to various issues, these system files may get corrupted and show performance issues such as the occurrence of a blue screen. In such a situation, it becomes necessary to repairing corrupted Windows system.

    System File Checker (SFC) and Deployment Image Servicing and Management (DISM) are two such Microsoft utilities, which are used to repair the corrupted Windows system files. This blog reflects the information about both the utilities and the procedure with the help of which the Windows system files can be repaired.

    More on SFC & DISM Utilities

    System File Checker was first introduced as a GUI utility in Windows 98. In Windows Vista and Windows 7, the utility is integrated with Windows Resource Protection. SFC scans and restores corrupt system files by replacing the corrupt files with the cached copy of the files from the DLL cache stored at location Windows\System32\DLLcache.

    Normally, there is no necessity of using DISM utility once the SFC utility has been run. However, in case the SFC fails to run or is not able to replace the corrupt system file with a healthy one, it is necessary to run the DISM utility.

    Procedure to Repair Windows Files with SFC and DISM Utilities

    In this section, we have explained the process with the help of which the user can repair the corrupt system files with the assistance of SFC and DISM utilities. Follow the below-mentioned procedure for doing this:

    Running SFC Command:

    • Right-click on Command Prompt option and select Run as administrator

    How to scan for (and fix) corrupt system files in windows

    • In the command prompt window enter the command

    C:\WINDOWS\system32>sfc /scannow

    How to scan for (and fix) corrupt system files in windows

    • Press Enter and let the system run a full scan.

    Do not close the command prompt window. It will take around 10-15 minutes for scanning the entire database for corruption. When the corrupt system files are repaired following message is displayed:

    How to scan for (and fix) corrupt system files in windows

    However, in case a message is displayed DISM utility should be used.

    Running DISM Command:

    The DISM command is used to fix the corruption of the component store that prevents the SFC from working in a proper manner. To run this command perform the below-mentioned steps:

    • In the command prompt window enter the command:

    C:/WINDOWS/SYSTEM32> DISM /ONLINE/ CLEANUP-IMAGE/restorehealth

    How to scan for (and fix) corrupt system files in windows

    • The progress bar might get stuck at 20%. Do not worry as this is a normal thing and will not affect the procedure.

    If the above command makes some changes, restart your computer and run the SFC command again.

    Note: It is to be noted that the DISM utility is not available in Windows 7 and earlier versions.

    Conclusion

    SFC and DISM utilities are the best utilities to repair corrupt Windows system files. However, it is to be noted that whilst SFC utility is available in all Windows versions, DISM is only available in Windows 8, 8.1, and 10. Therefore, for Windows 7 and above versions, other utilities can be used instead of DISM.

    Windows file system/registry corruption.

    Resolution

    In case you have Windows installation media (CD/DVD disk or .iso image), please do the following:

    Make sure Windows is connected to the Internet.

    Insert CD/DVD or put an .iso file to the easiest location on the Mac to use it later.

    From Mac top menu choose Devices > CD/DVD

    If you use physical CD/DVD, choose CD/DVD drive from the list.

    If you use .iso image, choose Connect image. and navigate to the image location.

    Double-click it and check that it appeared inside Windows as drive D:

    In Command Prompt execute the commands from step 7 one by one changed in the following way:

    where D: is the Windows installation image mounted in a virtual drive.

    Wait until the operation is completed. This usually takes 20-30 minutes.

    Restart the virtual machine.

  • If the situation did not change after the restart, the only thing left is to reset Windows.
  • If Windows updates fail to install, the operating system repair method from the official Microsoft knowledge base may help.
