Get-CimInstance : A general error occurred that is not covered by a more specific error code.

Hello, the Get-WindowsAUtoPilotInfo.ps1 PowerShell scripts returns the error below on computers with latest Windows Updates (May 2022); it seems the KB5013942 is causing it (links: Microsoft Q&A, Reddit).

Get-CimInstance : A general error occurred that is not covered by a more specific error code.
At C:\Program Files\WindowsPowerShell\Scripts\Get-WindowsAutoPilotInfo.ps1:211 char:17

C:\Program Files\WindowsPowerShell\Scripts\Get-WindowsAutoPilotInfo.ps1 : Unable to retrieve device hardware data (hash) from computer localhost

Removing the KB above resolves the issue, however on some environment it isn't possible (Windows says this is a required security update and cannot be removed).

On a deep investigation (WMI Explorer), it appears there is no Instance for the class MDM_DevDetail_Ext01 under root/cimv2/mdm/dmmap namespace, causing the error above.

Maybe you already know about it, and I also understand it isn't a script issue, but more a WMI related issue.

What are your thoughts ?

Thank you, Luca
