Phantom NICs in Converted HyperV VMs

Susan Bradley blogged about it here. If you convert a physical machine to virtual, the OS will complain about the NIC still being installed. Worse yet, you can’t see it in the Device Manager.

So, open up a command prompt and tell the system you really want to see it in the Device Manager:

SET DEVMGR_SHOW_NONPRESENT_DEVICES=1

Now open up the Device Manager and you can delete that phantom NIC.
