You will need to rate your computer's WEI (Windows Experience Index) score at least once before.
This is only for fun and show, this does not increase performance!!!
To restore original scores just re-rate your computer's WEI (Windows Experience Index) score
1. Open up Windows Explorer & Browse to C:\Windows\Performance\WinSAT\DataStore.
2. Click on the most recently created XML file there (its something like this….2009-07-05 01.12.28.985 Formal.Assessment (Initial).WinSAT)
3. Open above file fine in notepad or wordpad and make changes to following selected part shown in below image.
4. Save the file and open Performance Information and Tools (Right click on Computer-> Properties -> Windows Experience Index)
TRY IT AND HAVE SOME FUN......
