OK guys I need some advice from the pro's around here so here's the situation. Some friends of mine are in school and got the student discount on a Win7 upgrade disc so it was amazingly cheap, anyway, we all know you can't upgrade from XP to 7 directly, only from Vista, so upon my suggestion they went out onto the interwebs and downloaded a Vista Ultimate iso with some sort of oem loader built in, figured that would be good enough being as it would only be installed long enough to then upgrade to 7, anyway long story short. The 7 upgrade he bought is Windows 7 Pro, and we just found out you can only upgrade to 7 Pro from Vista Business, so my question.... Is there anyway to simply swap slp keys and have it be business? or will it be more involved, or worse yet not even possible. A thousand thanks to any and all help you guys can throw my way.
