How to Increase Windows Experience Index(WEI) in Windows 7

by Arpit Roy on August 22, 2011

The Windows Experience Index measures the capability of your computer’s hardware and software configuration and expresses this measurement as a number called a base score. A higher base score generally means that your computer will perform better and faster than a computer with a lower base score, especially when performing more advanced and resource-intensive tasks.

Each hardware component receives an individual subscore. Your computer’s base score is determined by the lowest subscore. For example, if the lowest subscore of an individual hardware component is 4.1, then the base score is 4.1.

The scores currently range from 1.0 to 7.9. There are some applications that take the WEI into account for running. If your Score is less than the desired value, the application won’t run on your computer. But there is a trick to increase your score without making any hardware changes.

1) Type %windir%PerformanceWinSATDataStore in the start menu search box and press enter.
