Windows 11

Should I use SFC or DISM?

SFC checks protected system files. DISM checks the Windows component store.

TRY THIS FIRST

Identify what you need to check

For suspected servicing corruption, start with the DISM check below in PowerShell as administrator.

Diagnostic check · Administrator required · Writes logs; does not repair

PowerShell

DISM.exe /Online /Cleanup-Image /ScanHealth

Result: Use what you find to choose the next step.

Still not working?

If corruption is found, use the guide for the DISM repair and SFC sequence. Neither tool fixes every driver, app or hardware problem.

Check the result: Repeat the original task after making one relevant change. If the problem returns, keep the exact message and time.
