Like many others I have upgraded from Win7 to Win10 and have run into problems trying to activate the license for the XP Mode VM in Hyper-V. The XP Mode VM starts up just fine but I get prompted for activation during logon. I don't need to use it in 'XP Mode', just a regular XP VM will do just fine.
I understand that XP Mode used some special licensing that was tied to the Win7 host which is fine & I realise to use it elsewhere I would need an XP license - I actually have a valid (separate) XP Pro license but this doesn't work on the XP VM in Hyper-V!
(If only I had never used XP Mode under Win 7, and just used a normal XP VM in virtual PC I would never have had this problem!)
So I was wondering whether there is any way to change the XP Mode VM in Virtual PC to not be 'XP Mode' ie. just a regular XP VM? I am sure that this would work just fine then when moving to Hyper-V.
After much time reading other info around the web I managed to sort this out, this is what I did:
My windows 7 XP Mode vm is now running as a regular vm under Hyper-V on windows 10.
