Does your store repair people's computers? If someone's comp is fucked and they tell you to throw it away cuz they are getting a new one, before you gut it and trash it, get the windows license off the case. We did that shit all the time at my old job. Made me a bit oh teh cash moniez. We have 7-8 working comps right now, i think all but one have XP, and we only paid for a couple of licenses, snatched the rest off trash computers.
