Hyper-V 2012 WMI VBS

Hi all,

In Hyper-V 2008 R2 I used the following code to check for VHDX files (snapshots). This doesn't work anymore in Hyper-V 2012 R2.

I've noticed the WMI service changed to \\.\root\virtualization\v2

Thing work fine then except for the Resource type 'Microsoft Virtual Hard Disk' doesnt exists anymore. It's a 'Synthetic' harddrive now. When I change the code to reflect to the new
name I cannot get an object anymore from ResourceAllocationSettingData.Connection(0).

Can anyone help me to get this script working in 2012 R2?

With regards,


Set objWMIService = GetObject("winmgmts:\\.\root\virtualization")
result = ""

Query = "select * from Msvm_ComputerSystem where caption='Virtual Machine'"
Set GetComputersystem = objWMIService.ExecQuery(Query)

For Each obj In GetComputersystem
    Query = "Associators of {" & obj.path_.Path & "} Where ResultClass=Msvm_VirtualSystemSettingData AssocClass=Msvm_SettingsDefineState"
    Set VMSettingDatas = objWMIService.ExecQuery(Query)
    For Each VMSettingData In VMSettingDatas
        Query = "Associators of {" & VMSettingData.path_.Path & "} Where ResultClass=Msvm_ResourceAllocationSettingData AssocClass=Msvm_VirtualSystemSettingDataComponent"
        Set ResourceAllocationSettingDatas = objWMIService.ExecQuery(Query)
        For Each ResourceAllocationSettingData In ResourceAllocationSettingDatas
            If ResourceAllocationSettingData.ResourceSubType = "Microsoft Virtual Hard Disk" Then
                vhdpath = ResourceAllocationSettingData.Connection(0)
                If InStr(1, vhdpath, ".avhd") Then
                    Debug.Print "Virtual Machine : " & obj.ElementName & " has an active snapshot"
                End If
            End If
