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).
