How to check your Windows Performance or Experience Index

Posted by TechGeek on June 23, 2011

Windows 7 has introduced a nice feature called Windows Experience Index. The Windows Experience Index actually rates your hardware and software capabilities. It will then create a base score on which you can measure your computer’s capability. Generally, a higher base score means your computer is very good in performance than with lower base score computer.

You can use this base score to buy any software or hardware that will match with your computer’s base score. The base score is lowest subscore of your hardware or software. The Windows Experience Index assesses key system components on a scale of 1.0 to 7.9. This feature helps you to advance your computer performance. You can upgrade your computer with better hardware and software for better performance. You can then measure the new Experience Index by updating the score button.

As you can see in the above image, the base score is lowest subscore and it is related to Graphics. The Windows Experience Index is generally measured on fallowing components,
