Hello, I used the old Lenovo Key that is probably going to get blacklisted in 3 weeks when Windows 7 comes out. Therefore, I would like to change it to one of the 2 other OEM keys available. Is there any easy what that I can do that? My Windows 7 is still activated and works perfectly, but I never followed the "If it ain't broke, don't fix it" mentality. Sincerely, -R.
