It has been sitting at the boot animation for a while in VirtualBox.

Only one way to find out if it works in a VM.

It seems I have never received a clear answer on this. I have a retail (non-OEM) version of Windows 7 installed right now. If I upgrade to Windows 10, will I have a version locked to my PC or can I transfer it when I finally upgrade from my “ancient” Phenom II?
