First of all, have a Happy New Year!
Several people asked me ‘Why did Microsoft remove the System Experience Index from Windows 8.1′? Well, you might indeed be wondering why, but the fact is that it didn’t really go anywhere since it’s still there, but not graphycally.
So, if you want to score your PC in Windows 8.1, you have to run the Windows System Assessment Tool from command line (is there any other way?), by using the winsat command in an elevated Command Prompt. You have the option of assessing your Desktop Windows Manager (system graphics capabilities), CPU, Internal Memory, Direct 3D, Disk drives and some other features. Of course, you can also run all of these under a single test (formal test).
However, given the complexety of the output shown by Windows System Assessment Tool, I suppose that Microsoft either prepares something for Windows 8.next when it comes to the Experience Index or their planning to completely remove WEI from the next version of Windows. You still have to keep in mind though, that according to this Windows page (What is Windows Experience Index), WEI typically scores from 1.0 to 7.9 and that in a PC powered by a 64bit processor with 4GB (or less), your memory score will drop to 5.9 and therefore your overall score will also drop to 5.9. Even though, I’ve assembled a PC several months ago where I achieved scores of 8.1 in a row. Therefore, I might say that either the page is outdated or the rating system is about to get some updates, don’t you think?
