Short for Windows Experience Index, WEI is a score of how a computer's hardware matches up with the performance requirements of software programs. The higher the score, the better your performance in Windows and with software programs is. The picture below is an example of what the Windows Experience Index looks like in Windows 7.

Microsoft Windows Experience Index

The WEI is available for computers running Windows Vista and Windows 7. For Windows Vista, the WEI score can be between 1.0 and 5.9 and for Windows 7, the score can be between 1.0 and 7.9. The WEI consists of five components that make up the final score: processor, memory, 2D graphics, 3D graphics, and disk. As more advanced and powerful hardware becomes available on the market, the highest possible score increases as well. A bonus of looking at a computer's WEI score is that it helps determine what the best hardware upgrade would be to improve performance the most.
