What Is The Windows Experience Index?

Windows Experience Index (WEI), one of the hundreds of features introduced with Windows Vista, is designed to help you better understand your computer's capabilities. It scans your computer hardware and assigns it a score after running a number of tests. These ratings help users in purchasing software and games. For instance, a base score of 5.2 means that the PC will run an application or a game if the WEI score of the game or application is less than, or equal to 5.2.
