Run an SFC scan

Windows 11 offers a number of ways to perform an SFC scan. The most straightforward way is to use the Command Prompt.

  • To do this, simply open the Command Prompt as Administrator and type sfc /scannow. The scan will then begin and will take some time to complete. If any corrupt files are found, they will be replaced with the correct version from Windows 11’s cache.
  • Another way to run an SFC scan is to use Windows PowerShell. To do this, open the PowerShell as Administrator and type Get-FileIntegrity-Scan-FullScan. Once again, the scan will take some time to complete but will replace any corrupt files that it finds.
  • Finally, you can also use the DISM tool to run an SFC scan. This tool can be found in the Windows 11 installation media. To use it, simply insert the media and navigate to the sources\sxs folder. From here, run the following command: dism /online /cleanup-image /scanhealth. This will start the scan and will take some time to finish. As with the other methods, any corrupt files that are found will be replaced with the correct version from Windows 11’s cache.
