Windows Experience Index refresh has an error

Problem

 * New hardware detected in Windows Experience and that message will not go away
 * Your windows experience index needs to be refreshed - won't go away

Resolution
Have you had an error where Windows Experience Index in Vista won't refresh?

Here is the fix I found with some help from a few forums.


 * 1) Go to C:\Windows\Performance\WinSAT\DataStore
 * 2) Delete all of the files
 * 3) Reboot (might not be necessary)
 * 4) Rerun the assesment

This was tested on an HP Laptop with Vista x64 and a GeForce Go 7600 (Nvidia).
