hey guys after checking the forums I could not find an answer to my question. Let's say I formatted 20 laptops that had windows xp on it but now I wanna upgrade them to windows 7. What's the best way to get 20 of these cd keys.. Obviously I could use a validation crack however I would like to sell these and not end up in jail from selling them on eBay. Should I just save myself the hassle and sell them as no operating system. Thxx
