I am coming to Windows 7 from Vista 64bit Ultimate. On Vista I was able to get aero enabled and my system scored a 4.7 on the winsat tests. When I did a clean install and went to Windows 7 Ultimate 64bit, my aero doesn't want to initiate. I also cannot complete my winsat test because when it gets to hard disk it says could not measure storage performance. I put in the latest drivers form nvidia's website and I got aero for a few seconds at start up only for it to change back to basic. I have tried forcing aero with those registry edits. I have also tried the troubleshooting transparency and aero effects and it gives me aero for a sec then goes back to basic. The problem it lists is the Desktop Windows Manager to be disabled. I have tried stopping and restarting the Desktop Windows Manager but it only does the same thing as the troubleshooter. I have also tried putting it to high performance in power options and setting it to best visuals but no dice. My system: XPS 200 w/ pentium D 2.8ghz with an upgraded 9500GT and 2GB RAM This was just cleanly installed so application compatibility problems is not likely. I have done all windows updates. Thanks for reading! The help is greatly appreciated!
