The WMI database can become corrupted, leading to various system issues. This article provides a step-by-step guide to restore WMI after corruption.

Example of my WMI corruption (System Restore not supported from powershell)

Also verify with this command:

winmgmt /verifyrepository

Note: You should see wmi repository is consistent if the WMI repository is healthy. If you see wmi repository is inconsistent, it indicates that the WMI repository is corrupted and needs to be repaired.

The Fix

First check if you can salvage the repository by running the following command in an elevated PowerShell:

winmgmt /salvagerepository

Then proceed to reset the WMI repository by running the following command in an elevated PowerShell (if above failed):

Stop-Service winmgmt -Force
Remove-Item C:\Windows\System32\wbem\Repository -Recurse -Force
winmgmt /resetrepository
Start-Service winmgmt

Then for my case to restore the System Restore part of the WMI I ran this command:

mofcomp C:\Windows\System32\wbem\sr.mof

Then I tested it via the powershell commands Get-ComputerRestorePoint to pull existing restore points from system restore.
