DISM ScanHealth

Scan the Windows component image for corruption without running the RestoreHealth repair operation.

Risk: LowReviewed: 2026-09-17
DISM.exe /Online /Cleanup-Image /ScanHealth

When to use it

Use when you need to assess component-store corruption before deciding on repair.

When not to use it

A ScanHealth result is not itself a repair; use RestoreHealth only when the diagnosis calls for repair.
