Hyper-V Server VM stuck at boot and I cannot delete it

I am using Microsoft Hyper-V server with Admin center. Admin center says: VM Status: Paused-Critical Powershell says: VM status : In service. After server restart one of the virtual machines is stuck at starting. I tried stop the VM via Powershell, unable to delete. Unable to kill vmwp.exe process by ID via Powershell. The files are in use... Rebooting HOST Server - no luck, same...

Solution 1:

Power off your host, mount disk with VMs with some other Windows Server box and delete VM files manually from there.

P.S. Don't use Windows Admin Center (WAC), use PowerShell to manage and monitor your Hyper-V cluster. WAC is just one big can of worms (and bugs).
