Knowing that I had an upgrade product key coming for Win 7 Professional, I made sure that I installed the Professional RTM version. So the versions match. So I am left with the question: Will an upgrade product key entered after installation activate a clean install?
As I recall, the RTM iso gave me the opportunity to do either a clean install or an in-pace upgrade. I was tired of all of the crap collected from XP and Vista, so I decided to do a clean install. However, because I had Vista, I am eligible for upgrade pricing. Since the install media is the same, is there a registry setting that designates whether I am eligible for an upgrade product key?
