Friend wanted me to upgrade his Acer laptop with home basic pre-installed to Vista Ultimate. So i "foolishly" did. Now the whole Build 6000 - This copy of Windows is not genuine is preventing him from using his laptop. So I was looking around about OEM and activation, and was wondering if http://www.mydigitallife.net/2007/0...indows-vista-as-oem-for-acer-motherboardbios/ is the right and easiest solution to use. His key is legit, but I'm wondering if installing a RC vista home basic will take his OEM product key. If so, please tell me. If not, will the page above help me install home basic back onto his computer and have it activated and never having to worry about wga again.
