This article will introduce you with the freeware to rate Windows 8.1 system using Windows Experience Index, named "WinAero WEI Tool''.

We all know that Windows Experience Index (WEI) is the scale that rates a computer between 1.1 to 9.9 after evaluating performance of key hardware components such as the CPU, disk drive, and graphics card. This feature uses WEI engine to calculate the performance of device running Windows. Unfortunately, the WEI feature has been removed by Microsoft in Windows 8.1 due to less usage, but the good thing is that WEI engine remained embedded in the current stable release, Windows 8.1.
