How to Update or Refresh the Windows Experience Index (WEI) Score in Windows 8 and 8.1
The Windows Experience Index (WEI) 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 piece of hardware in your PC gets its own score called a subscore. The total base score for your PC is determined by the lowest individual subscore, rather than an average of them all. You can view the subscores to see how the hardware you care most about is performing, which can help your decide whether to upgrade some parts of your PC.
This will show you how to update or refresh your Windows Experience Index (WEI) score in Windows 8 and 8.1 to help measure the capability of your computer.
