If the scan doesn’t find any issues, you’ll receive a message saying ‘Windows has scanned the file system and found no problems. No further action is required.’ However, if any corrupted files are detected, they will be repaired automatically.

You can run an SFC scan followed by a DISM scan to find and fix corrupt files on your system. Here are the steps:

A DISM scan repairs OS issues and scans for corruption. It goes beyond the SFC scan by checking recovery and boot sectors for corruption and can restore file resiliency if needed.

To perform a DISM scan, enter the following commands into Command Prompt one at a time:

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth
