Ever since the Vista days, Windows provided a “Windows Experience Index” score in your My Computer properties. The WEI score was supposed to be a numerical indicator of your PC’s brawn. Powerful PCs received higher scores, and so on.

Unfortunately, the WEI’s scoring criteria weren’t well known, and it placed odd, seemingly artificial caps on the highest possible scores. (Windows 7’s cap was 7.9, while Vista’s was 5.9.) Whether for these or other reasons, the WEI never seemed to catch on, and it’s nowhere to be found in Windows 8.1.
