WMI is required for our software to install and work. If you purchased the computer from us and it is still under warranty then this is covered. If the computer was not purchased from Pinogy or has exited it’s warranty period then you will need to consult a local IT professional to have this done. There is a chance of the computer becoming non-functional if this is attempted and require a complete reinstall of windows.

 

 

 

 

 

 

 

You can receive error 0x80041010 from multiple applications that call WMI.

 

 

 

Confirm WMI is Broken:

Launch the WMI MMC snapin by Start -> Run -> then enter WMIMGMT.MSC

Right click WMI Control (Local) and click Properties

If WMI is working properly then it will show that Working Properties. If you see Invalid class then your WMI is not working correctly.

Troubleshooting:

The first step is to download the Microsoft WMIDiag Tool. It will analyze WMI and give you a report with any issues it finds. Unfortunately Microsoft has removed the WMIDiag tool so we can no longer use this tool.

When you run the downloaded .EXE it will ask you where to extract the files. Once extracted right click the WMIDiag VBScript and click Open with Command Prompt

Here is what the script looks like while it runs:

Once complete you will get a text file of the results. Here you should be able to narrow down the cause of your WMI issue. In this case there are issues with .MOF registrations.

Resolve MOF Registration Errors:

To resolve MOF Registration errors the following commands need to be ran from an elevated command prompt. It will reregister all .MOF files with WMI.

PowerShell 1CD C:\Windows\System32\WBEM dir /b *.mof *.mfl | findstr /v /i uninstall > moflist.txt & for /F %s in (moflist.txt) do mofcomp %s

Here is what the command looks like while it runs:

Once finished check WMIMGMT.MSC to see if it is populating the Properties correctly.

 

 

Rebuild the WMI Repository

If needed we can fully rebuild the WMI Repository. We do not do this on any computer that is out of warranty and/or did not come from us. We can send these instructions to their IT techs.

These instructions came from

https://serverfault.com/questions/795583/wmic-os-alias-not-found

It bases this on a failed WMIDiag tool response but as the tool is no longer available we will presume that the WMI repository is not healthy or giving false healthy responses.

To fully rebuild the WMI Repository follow these steps:

  1. Disable and stop the winmgmt service

  2. Remove or rename C:\Windows\System32\wbem\repository

  3. Enable and start the winmgmt service

  4. Open a CMD prompt as Administrator

  5. In the CMD prompt Navigate to C:\Windows\System32\wbem\

  6. Run the following command:

    for /f %s in ('dir /b *.mof') do mofcomp %s

Note: This will take a minute or so to complete.

  1. Now run the command:

    for /f %s in ('dir /b en-us\*.mfl') do mofcomp en-us\%s

  2. Reboot the computer
