I have a Dell XPS for two years...Awhile ago I contacted Dell as they did not send a disk to program a fancy keyboard (Function Keys)..anyways, instead they had sent me a new XP-Pro operating system disk..Nice sealed package but it wasn't what I needed...Now two years later I have a Mac Pro (bought yesterday !!!) and I would like to use that Dell XP-Pro disk for Bootcamp/VMfusion ...Is there any issues both functionality and legally..??
