Set up Vista on Hyper-V under Windows 10, cannot connect to internet
Dell XPS 8500 host running Windows 10 Pro x64 build 14393, Vista Ultimate SP1 x64 Gen 1 guest.
I installed Vista in a Gen 1 VM but it cannot find a network adapter. I have tried both of my connectors (Ethernet external and WiFi external) but no effect. I have deleted the network adapter in Settings and added it back but no effect.
I had Vista running this way fine a few months ago so I used the archived .vhdx file in a second Gen 1 VM but it didn't do any better than the clean install in the first VM.
Obviously I am missing a step that I have forgotten. Advice appreciated.
