Windows Experience Index

Windows Experience Index (WEI) is a performance metric that Microsoft introduced with Windows Vista and it is also present in Windows 7.It was made to give the user an idea about how well a computer will run Windows.

In Windows 7 the Windows Experience Index assesses the performance of the components in a computer on a scale from 1.0 to 7.9. The WEI score is determined by the lowest subscore of an individual component. This means that, for example, if you have a 5.8 subscore for the hard-disk drive and the score for the other components is higher than this one, the base score will be 5.8.

In order to assess your computer performance, do the following:

1. Right click on Computer and click on Properties (or press the Windows Key+Pause).
2. If you can see System rating is not available you should click on it because your system wasn’t rated.  If a score appears then the system was rated.
3. Click on Rate this computer. It is recommended that you close all other applications.
4. The process will take some time during which you should not intervene in any way even if your screen may flicker or go blank.
5. You can now see your Windows Experience Index.

If your computer already has a score but you want to update it you should do the following:

1. Repeat step 1 from the above procedure.
2. Click on Windows Experience Index.
3. Now click on Re-run the assessment and wait while the calculations are being made.
4. Your new score will appear.
