Re: I still have two XP instances
ref the XP VM thing. XP is fine on a VM as there was nothing prohibiting you from doing so, any old sticker was transferable to VM and the 90 day transfer rule was also acceptable.
Windows 7 on the otherhand is a fucking nightmare to license on VM. it is cheaper to use server. you cant use a desktop license as it is prohibited. you need specialists to get you licensed.
