Which VM to Blame?

You have a hyper-v host and the disk space is reaching its limit although you have 4TB of storage.


Get-VM does not really tell you about the disk space each VM occupies. The space is mainly taken by the VHDs.

The PowerShell script can be downloaded from TechNet Gallery: Get Disk Space Used by VMs
