When you see Windows Resource Protection Found Corrupt Files but Was Unable to Fix Some of Them in sfc scannow, it means you need to repair the boot files. Follow our guide to do so.
When using the System File Checker (sfc) tool and running the sfc /scannow command to repair missing or damaged system files, you might encounter the error message: "Windows Resource Protection found corrupt files but was unable to fix some of them." This error means that the sfc /scannow process failed, and you may need to manually repair the corrupted files.
The System File Checker is a built-in Windows utility that works alongside Windows Resource Protection to safeguard important system files, registry keys, and folders. You can run the tool through the Command Prompt by using the sfc /scannow command. This command scans all protected system files and tries to replace any corrupted ones with a cached copy stored in a compressed folder at %WinDir%\System32\dllcache.
In most cases, the sfc /scannow command should automatically fix any detected issues. However, if the required file is missing from the cache or is itself corrupted, the tool will display the error message about being unable to repair some files. If you encounter this issue, don’t worry. You can resolve it by following practical steps to manually repair the files.
There are some situations where the System File Checker may stop working and display the error message, "Windows resource protection found corrupt files but was unable to fix some of them." To address this issue, you can try some general troubleshooting methods to resolve it quickly and effectively.
If you encounter the error "Windows Resource Protection found corrupt files but was unable to fix some of them," you can use the DISM (Deployment Image Servicing and Management) utility to repair the Windows image. This tool can address corruption in the system files by utilizing the Windows Update component to replace damaged files with clean versions.
Since the SFC tool relies on local storage for replacements (which might also be corrupted), DISM offers an alternative by accessing Windows Update. Before running DISM, ensure you have a stable internet connection. You can use the RestoreHealth command to scan and repair the Windows image automatically. Follow these steps:
Press Windows + R to open the Run dialog box, type cmd, and then press Ctrl + Shift + Enter to launch Command Prompt with administrative privileges.
Enter the following command and press Enter to check for corruption, log it, and repair the issues:
dism /Online /Cleanup-Image /RestoreHealth
If you are in repair mode using a Windows DVD/USB, use this command instead:
Dism /Image:C:\ /Cleanup-Image /RestoreHealth
After completing the DISM process, restart your computer. At the next startup, open Command Prompt as an administrator and run the sfc /scannow command to check if the issue is resolved.
Another way to fix Windows Resource Protection found corrupt files but was unable to fix some issue is running SFC utility in Windows Recovery Environment (WinRE).
Step 1. Boot from Windows installation DVD and choose Advanced Boot Options. Then select "Repair Your Computer".
Step 2. Choose your target system. In the recovery tool panel, choose Command Prompt.
Step 3. In the command prompt window, type sfc scannow and press Enter.
However, if the sfc scannow found corrupt files but was unable to fix some of them error is still occurring, move to the final method below to replace all Windows components and resolve the issue.
