Since Windows 10 doesn't include an XP mode, is it possible, on a new PC that includes a Windows 10 OEM licence with Windows 7 downgrade rights, to install Windows 10 and then install Windows 7 as a virtual machine under Windows 10? And then use XP mode within the Windows 7 virtual machine.
Or to put it another way, does the OEM licence allow you to install both Windows 10 and Windows 7 on the same machine (one as a virtual machine), or can you only install one or the other.
Failing that, what are the alternatives for licencing a Windows 7 or XP VM on a Windows 10 PC?
I've never understood Windows licencing.
