I've come across 4 copies of XP Pro OEM. The copies still have the COA attached, but they are opened. I thought about selling them, but I don't think I can if they have been registered. The computers they would have been installed on are now in a trash dump. Judging from the last comp tech that worked here, he probably used a corporate copy for all the comps. Anyway... long story. Anyway to tell if its been activated?
