I have been using Windows 7 since the RC and have updated and activated all the way to release 7264. I recently installed RTM on my C: drive and removed XP. So on C: I have RTM and on D: I have 7264. I honestly can't tell the difference in appearance however, Windows 7 7264 is much smoother, my video card does not crash or lock up, and my Windows Experience rating is .7 points higher. Wtf, how can the RTM be more buggy than a release candidate. I do not have any issues with 7264. RTM is like the sauce a chef tweaked too much or in this case M$.... If anyone knows a way of permanently activating a pre-RTM release, please help. I am currently activated until next June..
