Windows Experience Index or WEI is a feature included in Windows 8, Windows 7 and Windows Vista that evaluates the performance of critical hardware components such as the processor, drive and graphics card. It helps the PC to obtain a value between 1.0 and 7.9. The score helps you find a floor model that meets your needs.

Normally, a PC with a score of 2 is sufficient for basic computer tasks such as surfing the Internet. Graphics intensive software often requires a 3 or more. WEI plays an important role in this regard. If you cannot update WEI, you can try the following.

Right-clicking on your computer and clicking Properties takes you to a page that displays, among other things, your WEI machine.
