Windows Resource Protection detected corrupt files: 5 fixes
An SFC scan on Windows can fix many system stability issues, but what if you get a Corrupt files detected by Windows Resource Protection error? Try these fixes.
If you are using Windows, you can use the System File Checker (SFC) Tool to fix many buggy operating system issues. For example, running an SFC scan can help detect corrupt system files and replace files with working ones.
You can use it to fix Windows 11 crashing, fixing a keyboard that isn’t working, or spotting (and possibly fixing) other issues. For example, if you see a Windows Resource Protection found corrupt files error message like the one below, you’ll know you have a problem.
The error indicates that SFC found corrupt system files but was unable to replace the files with working ones. After receiving the error, you have a few options to repair your PC.
Here are five ways to fix the corrupted files detected by Windows Resource Protection error.
1. Run a DISM scan if SFC cannot repair corrupt files
While performing an SFC scan, it will replace corrupted files with known working files. However, System File Checker may not have the correct files to replace corrupted files.
Instead, you can run a Deployment Image System Management (DISM), which will check Windows servers to replace damaged files.
To run a DISM scan, follow these steps:
- Right click on the To start up button and select Windows terminal (administrator) from the menu.
- Enter the following command in the terminal and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth
Note that it can take a while for the scan to run and it is not uncommon for it to appear stuck at 20%. Do not close the terminal window until the scan is complete.
Once the scan is complete, run an SFC scan again to see if you still receive the error.
2. Run SFC scan in safe mode
The corrupted files detected by Windows Resource Protection error can be caused by running operating system processes and services. Starting Windows in Safe Mode only loads the minimum drivers and services to start. After booting into safe mode, you can then run an SFC scan.
To note: If you are not on Windows 11 yet, you can start Windows 10 in Safe Mode.
To start Windows 11 in Safe Mode, follow these steps:
- Click it To start up button or press the windows key and head to Start > Settings > System > Recovery.
- Scroll down the menu and click on the Restart now button next to Advanced start option.
- Click it Restart now button when the verification message appears.
- Your computer will boot into the Windows Recovery Environment, and from there you want to access Troubleshooting > Advanced Options > Startup Settings. To choose Enable Safe Mode with Command Prompt.
- Now that you are in safe mode, launch terminal as administrator and run an SFC scan.
3. Uninstall Windows Updates
If you receive the error Corrupt files detected by Windows Resource Protection after a Windows update, it may be buggy and conflicting with other system files. In this case, you can uninstall the cumulative update.
To uninstall a Windows Update, follow these steps:
- Open Start > Settings and click on Windows Update in the lower left corner of the menu.
- Under the More options section, click Update history from the list.
- Scroll down the list to Related Parameters section and click Uninstall updates.
- Right-click on the troublesome update and select Uninstall and click Yes when the verification message appears.
Once the update is uninstalled, restart your system and run the SFC scan again to see if it fixes the error.
4. Use a restore point
If the SFC and DISM scans still don’t help, you can recover your PC from a system restore point, provided you have one.
To undo the operating system changes and get your PC working again, follow these steps:
- Press the Windows key, type restore pointand choose the Create a restore point top result option.
- In the System Properties window, click the System Restauration button.
- Navigate the on-screen wizard and choose the restore point you want and click following.
- Once you have selected the restore point you wish to revert to, click on the To finish button.
Your system will restart and the restore point utility will apply the changes and get your PC back to working order.

If you are still getting the Corrupt files detected by Windows Resource Protection error, you can go one step further and reset your PC. Note that a PC reset is a “nuclear option” and will kill your apps. Also, your personal files might be lost in the process, so back up your PC first.
To reset your PC, follow these steps:
- Open Start > Settings and open System.
- Scroll to Recovery Options.
- On the next screen, click the PC reset button.
- Now choose to keep your files and settings or delete everything and reinstall Windows.

Repair Corrupt System Files in Windows
Microsoft has come a long way in providing a well-built and stable operating system. Having corrupted system files isn’t as common as it was in the beginning, like Windows 98, for example, but it can still be a problem. If corrupted files are found during an SFC scan, running a DISM scan will often resolve it. However, you may need to take more drastic measures like a factory reset or a complete reinstallation.
SFC and DISM utilities can fix many issues on Windows, such as Microsoft Teams not loading or Windows 11 not working after an update. It’s not just for software issues either. For example, you can use the scan to fix USB not working or HDMI not working on your PC.
