The component store has been corrupted.

  • Symbolic name ERROR_SXS_COMPONENT_STORE_CORRUPT

Failure

What it means

A file the component store needs is missing or damaged, so servicing cannot apply the update. This one usually does not clear itself with a retry.

Real causes

  • A CBS manifest is corrupted or missing.
  • Files in WinSxS were removed or damaged, often by disk cleanup tools or storage-level problems.

What to do

  1. Run Dism.exe /Online /Cleanup-Image /RestoreHealth, then Sfc.exe /Scannow, then restart.
  2. If the online repair cannot find its source, supply matching media: DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess
  3. The repair source build must match the device build.
  4. If DISM cannot repair the store, an in-place upgrade with matching media is the realistic next step, and it preserves apps and data.
