Not to sure if this is the right place to post this but, if I was currently using a "black" version of Vista on two pcs, can an upgrade be used if I purchased it? Don't know if this is too early to ask if anyone even has an answer to this but if I were to buy the upgrade to Windows 7 Ultimate (Windows 7 Upgrade checker says my pc can handle this) and upgrade this "black" Vista, can it legitimize the original os? What I mean is would it not give me any problems indicating I am using counterfeit hardware. Just wondering whether to buy the upgrade or full
