Windows update error 0x80073712 .

Hi Maurizio,

This code means Windows Component Store (WinSxS) is corrupted or missing update manifests, which prevents the servicing stack from installing updates. If DISM /Online /Cleanup-Image /RestoreHealth did not fix it, mount a Windows ISO that matches the exact OS build and run DISM /Online /Cleanup-Image /RestoreHealth /Source:wim:X:\sources\install.wim:1 /LimitAccess (replace X: with the ISO drive) so DISM can repair the store using clean files. After DISM completes successfully, run sfc /scannow and attempt Windows Update again. If DISM still fails with errors such as 0x800f081f, the supported fix from Microsoft is an in-place repair upgrade by launching setup.exe from the same ISO and choosing Keep personal files and apps. This rebuilds the servicing stack and typically resolves persistent 0x80073712 update failures.

If you find it's helpful, pleave give it a thump up or accept the answer, very much appreciate it :)

Harry.

Error 0x80073712 corresponds to ERROR_SXS_COMPONENT_STORE_CORRUPT, which means the Windows component store is in an inconsistent or corrupted state and can block Windows Update.

Since DISM and SFC have already been run and the error persists, the next steps are:

1. Review Windows Update corruption guidance
   • Error 0x80073712 is listed as a common corruption error that can prevent updates from installing. When DISM and SFC do not resolve the issue, further manual repair or advanced troubleshooting is required, as described in the Windows Update corruption article.
   • Check the Setup event log and CBS.log for related errors to confirm component store corruption and identify affected components.
2. Use advanced DISM repair options
   • The DISM article is intended for advanced/manual repair of Windows Update corruption. Follow its guidance for:
     • Running DISM with appropriate servicing options against a known-good source image if available.
     • Addressing component store corruption scenarios associated with ERROR_SXS_COMPONENT_STORE_CORRUPT.
3. If corruption persists after DISM
   • If repeated DISM repairs (with a valid source if required) and SFC still report corruption or Windows Update continues to fail with 0x80073712, the environment may require:
     • An in-place repair/upgrade of Windows using installation media, or
     • Escalation to support, as the corruption may be beyond what DISM/SFC can repair automatically.
4. Confirm other Windows Update errors
   • If other Windows Update error codes appear in parallel (for example, download failures, XML/metadata issues, or policy-related errors), use the Windows Update error reference to interpret those codes and address any additional configuration or policy problems.
