I attempted to delete a virtual machine from my 2012 hyper-v manager and received an error at the very end that there was a catastrophic error and it threw code 0x8000FFFF. I found an article online explaining what to do as deleting is no longer an option. It said to go to %systemroot%\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines, find the server in question, and delete it. OK, did that, but the vm is still showing in the hyper-v manager that I can't connect to (obviously), but also cannot delete. Is basically a ghost at this point. Any thoughts on how to remove fully at this point?
