Hello,

In first, Thank's for your great job !.
I use an unattend.xml file to send the hardware hash (Autopilot Enrollment)
With Windows 10 2004 all is good,
With 20h2 is not the same, it is the end for this method ?
Unattend.xml in AuditUser mode -> launch a Powershell who install Windowsautopilotintune to get the hardware Hash
If I check with a query Wmi, i can take the serial number but not the Class MDM_DevDetail_Ext01
Get-WmiObject -namespace root/cimv2/mdm/dmmap -class MDM_DevDetail_Ext01 return an error.
Do you Have already Tested ?

Sorry for my English...:)
Best regards,
Michel
