We all know about new feature "Windows Experience or Performance Index" in Windows Vista. Its a new feature which automatically calculates your system performance index based on the hardware you have. It can be between 0.1 to 9.9
Better system hardware, better Performance Index and better system performance.
"Windows Performance Index" is shown in "System Properties" which can be accessed by right-clicking on "My Computer" icon on Desktop and select "Properties" or from "Control Panel".
Using this trick, you can increase that Index upto 9.9.

The benefit of this hack is, there are a few features in Windows Vista which can only be used if your "Windows Experience Index" reaches the minimum requirements. So by increasing the Index manually, you can use those features.
Like You'll get toolbar in "Photo Gallery's Slide Show" while opening a wallpaper in Explorer.
How to:
1. Type following in Startmenu Searchbox / Run / Explorer Addressbar:
%windir%\Performance\WinSAT\DataStore
And Press <Enter>.
2. You'll one or more .xml files in the folder. Sort them by Date Created or look at their name. The file name will be in following format:
2007-11-08 22.23.17.858 Assessment (Initial).WinSAT.xml
Where "2007-11-08 22.23.17.858" might differ from machine to machine and Windows Installation date/time.
3. Open the latest file in "Wordpad" and goto line having <WinSPR>. It'll be approx. 12th line and will look like following:
<WinSPR>
<SystemScore>1</SystemScore>
<MemoryScore>4</MemoryScore>
<CpuScore>3.4</CpuScore>
<CPUSubAggScore>2.9</CPUSubAggScore>
<VideoEncodeScore>3.9</VideoEncodeScore>
<GraphicsScore>1</GraphicsScore>
<GamingScore>1</GamingScore>
<DiskScore>4.2</DiskScore>
4. Now you can edit the numbers between > & < and can increase them upto 9.9 as following:
<WinSPR>
<SystemScore>9.9</SystemScore>
<MemoryScore>9.9</MemoryScore>
<CpuScore>9.9</CpuScore>
<CPUSubAggScore>9.9</CPUSubAggScore>
<VideoEncodeScore>9.9</VideoEncodeScore>
<GraphicsScore>9.9</GraphicsScore>
<GamingScore>9.9</GamingScore>
<DiskScore>9.9</DiskScore>
5. Thats it. Save the file and check the Index again in System Properties. It'll 9.9 now.
NOTE: If you can't save the file, then take ownership of the file. For taking ownership, follow this tutorial:
Add Take Ownership Option in File / Folder Context Menu in Windows Vista
Also if you don't see the updated Index in System properties, then make sure there is no file having "(Formal)" in its name in the above mentioned folder. If its there, then delete it and you'll have updated Index.

Save the xml file to My Documents, and then delete the xml file in WinSat folder and replace it with your modified one.

This is old school. I found this out years ago, nice though. Also unlike what others have commented, this does NOT really boost your real time performance it ONLY changes the specs that is shown in the computer's properties. Now a real trick is changing the SYSTEM info and the Windows edition in the computer properties. If you wanna know that let me know.
Matthew
Also the only "extras" that you get for having a high score that is worth it is only available in Vista Ultimate(Dream Scene and you can get that without Ultimate) or 7(now this is worth it, you get a load of stuff here, but WEI only will recognize 7.9 and below).

HEY VG A SIMPLE WAY IS TO GO TO %SYSTEMROOT%\PERFORMANCE\WINSAT\DATASTORE THEN DELETE ALL FILES THERE THEN RERATE OR UPDATE WINDOWS SCORE THEN GO TO ABOVE PATH AND EDIT THE ONLY FILE THERE AND PUT ANY NOT ABOVE 9.9 AND THE DIFFERENCE IS THAT WHEN YOU CHANGE THE SCORE IT WILL SAY WINDOWS EXPERIENCED INDEX RATE AND NOT UNRATED AND PIC OF SCORE BLUE NOT BLACK
