I just returned to the Vista fold after a long stretch of a 98SE/XP situation, which I also combine with a Linux distro.
At first I kept formatting and installing again and again because I couldn't get Windows Experience Index to get past the Aero test, and the initial first boot couldn't do it either.
Finally I renamed /Windows/Performance/WinSAT/DataStore to DataStore.old and that enabled the test to finish.
But today I upgraded the NVidia driver to the latest and needed to run it again and renaming it didn't work. Over and over I tried different things such as deleting everything in the WinSAT folder (except the Windows Media tests which I think only come with a WMP install and I didn't want to mess with that) including taking ownership of the file that wouldn't let me delete it. Then I ran sfc/scannow, it put back the stuff. Still, no good.
Finally I clicked all the boxes for CREATOR/OWNER on the security tab for DataStore. It seemed to make the checks disappear afterwards, but when I ran the test for WEI it went ahead and updated my score.
Has anyone else had so much trouble running the test? As soon as it starts the Aero test, when the problem is happening, the mouse cursor will freeze and I must hit the reset switch on my computer to restart the computer. This happened with any NVidia driver, Microsoft or NVidia provided. And this had never happened before with all the Vista beta's, release candidates, or when I first bought and used the retail Ultimate upgrade dvd.
Also unlike before, running sfc /scannow gives final results all the time that there were some corrupted files and it couldn't replace all of them. The details in the log it mentions give no real clue what the problem is as far as I can tell. I just think this is related to the files dealing with that Performance folder and the permissions somehow not being set right by default to allow the tests to be performed or files to all be replaced by sfc.
Any ideas?
