Windows Experience Index in Windows Vista

[XSI]

I have heard that Windows Experience Index is a new feature built into Windows Vista. Can you help me as to what is the use of this feature and how to use it? I am asking so because I just want to know about it as I am running Vista on my system.

According to Microsoft, the "Windows Experience Index" feature in Vista is designed to help you better understand how well Windows Vista and other software will perform on your PC.

Your computer, running Windows Vista, is assigned a rating number called a "base score" that is achieved by measuring the capability of your computer's hardware configuration. This base score rating will help you to more confidently buy additional hardware, programs, and software that are matched to your computer's base score.

The scale of the Windows Experience Index ranges from 1.0 to 5.9. 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.

For example, if your computer has a base score of 3.3, then you can confidently purchase any software designed for your edition of Windows Vista that requires a computer with a base score of 3.0 or lower.
