Recently I've been getting this error, and I have no idea what triggered it. The documentation I found regarding this class is minimal and I'm not sure what I need to check or where to look in order to understand it and fix it.

System:

  • Windows Server 2012 R2 Datacenter Preview Build 9431
  • PowerShell Version 4.0 32bit and 64bit

Output:

PS > Get-WmiObject -Class "Msvm_ImageManagementService" -Namespace "root\virtualization"

Get-WmiObject : Invalid class "Msvm_ImageManagementService"

The class is still there, it now resides in a different namespace. It's in the namespace "root\virtualization\v2". It's also worth noting that the class has changed, previously used methods may not exist anymore.
