Symptoms

After running the command sfc /scannow, the following error appears:

Windows Resource Protection found corrupt files but was unable to fix some of them.

Cause

The sfc /scannow utility was unable to retrieve the required files from the Windows component store.

Solution

In this case, there is a need to try repairing the component store of Windows image using DISM. After restoring the image, you can use the SFC utility again to restore system files.

To repair corruption in the Windows image component store, use the RestoreHealth command of the DISM.exe. DISM will automatically download missing or corrupted files of the image from Windows Update servers.

Run the command: DISM.exe /Online /Cleanup-image /Restorehealth.
