WMI not working on win10 - all related services broken

Question

Hello all,

1)

PS C:\Windows\System32> Get-WmiObject -Class Win32_Product

Get-WmiObject : Invalid class "Win32_Product"

At line:1 char:1

• Get-WmiObject -Class Win32_Product
• CategoryInfo : InvalidType: (:) [Get-WmiObject], ManagementException
• FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

winmgmt /verifyrepository results in a return of WMI repository is consistent, so it doesn't appear to be corrupt.

Hi,

It looks like you're encountering an error with the Get-WmiObject cmdlet. The "Invalid class" error typically occurs when the specified WMI class is not available or not registered correctly on your system.

Here are a few steps you can try to resolve this issue:

1. Verify WMI Repository: Run the following command in an elevated Command Prompt to check if the WMI repository is consistent:

   winmgmt /verifyrepository

If it returns "Repository is inconsistent," you can try to repair it with:

   winmgmt /salvagerepository

1. Re-register WMI Components: You can re-register the WMI components by running the following commands in an elevated Command Prompt:

   cd /d %windir%\system32\wbem
   for %i in (*.dll) do regsvr32 -s %i
   for %i in (*.exe) do %i /RegServer

1. Recompile MOF Files: Recompile the MOF files to ensure all necessary classes are registered:

   cd /d %windir%\system32\wbem
   for %i in (*.mof, *.mfl) do mofcomp %i

1. Check for Missing or Corrupt Files: Sometimes, missing or corrupt system files can cause this issue. Run the System File Checker tool:

   sfc /scannow

If these steps don't resolve the issue, it might be helpful to check the Windows Application log for any WMI-related errors or events.
