Repair WMI Repository

Repair WMI Repository fixes Windows Management Instrumentation corruption that affects system management tools, scripts, and enterprise management platforms (SCCM, Intune, WMIC). It first verifies the WMI repository integrity, attempts a non-destructive salvage repair, and only performs a full repository reset if salvage fails. It re-registers core WMI MOF files, restarts the WMI service and its dependencies, and verifies basic WMI queries work after repair. WMI is critical infrastructure — SCCM hardware inventory, PowerShell system queries, and many monitoring tools depend on it. Medium risk because a full reset loses custom WMI classes. Takes about 3 minutes.

How to Fix

1
Verify WMI health: Admin CMD > winmgmt /verifyrepository
2
If inconsistent: try winmgmt /salvagerepository (attempts repair without rebuild)
3
If salvage fails: winmgmt /resetrepository (full rebuild — warning: loses custom WMI data)
4
Restart WMI service: Admin CMD > net stop winmgmt /y then net start winmgmt
5
Re-register WMI MOF files: for %s in (%systemroot%\system32\wbem\*.mof *.mfl) do mofcomp %s
6
Check for WMI filters: if using Group Policy WMI filters, verify they still evaluate correctly after repair
7
Or run RescuePC's Repair WMI Repository which safely verifies, salvages, or rebuilds WMI as needed
