Windows Experience Index in Windows 8.1

With the release of Windows 8.1, Microsoft is offering a lot of new things and has also removed some useful things from Windows. One of the important things some may miss is Windows Experience Index. For those who are not familiar with Windows Experience Index, it’s a benchmark tool from Microsoft that determine the performance of your computer. It analyzes your Processor calculations per second, Memory operations per second – Graphics by determining Desktop performance of Windows Aero and so on.

Microsoft first introduced this in Windows Vista. Microsoft removed the Experience Index from Windows RT but kept it on the original release of Windows 8 in October of 2012


I think it’s a bad move from Microsoft that they decided to kill of this feature. It was a nice way to benchmark a PC without any additional tools. Well, at least the geeks used to look at this score and compare the performance, but when it comes to average home users they couldn’t care less about this feature. Most of them didn’t even know that there is such a feature on Windows 7 or Windows 8.

Because of WEI I knew if I needed a Hard driver with better RPM or even an SSD on my laptop. But my guessing is Microsoft decided to kill this feature because it was less popular among the users. Lets face it, geeks are a rare breed when compared to the average home or business user, who doesn’t really care about these small changes.

There are speculations that Windows 8 removed this feature because Windows Store might do this job for them. Just like Google Play Store which will not let you installed a game that is not compatible. So I guess today if you want to check if a game is compatible with your PC you could visit Can You Run It.


This website will benchmark your PC and list the game that works with your PC. How it works is it looks at your computer’s hardware and system software to determine whether or not your current system can run a game. Recommendations are made on how to update or upgrade each component which does not meet the listed requirements. This patent-pending technology is called “Instant Expert Analysis” and it is provided by System Requirements Lab.

    Morons they are still removing desktop features and adding crappy apps no one wants. I will pass on 8.1 after what I say in the horrible preview. If Microsoft is not careful, they may end up losing their desktop monopoly as well.

    @Author [And Viewers] Be careful your spelling. The command is “WinSAT Formal -reset” not “Format” I saw a few other errors, but that was the critical one to run the index.

    Wow, wasn’t even aware this was missing in Windows 8.1 until I decided to see if my new SSD hit 7.9 in the WEI. Oh well, certainly not the end of the world. 3DMark and Heaven Benchmarks are the most reliable performance benchmarks I’ve seen.

    the command should be “winsat formal -restart”

    UGH. I literally just installed a SSD and wanted to see what my WEI jump would be. I searched and searched and could not find the WEI. At least finding this article stopped me from going crazy.

    anyway, it’s just a benchmarking tool. As I upgraded to 8.1, some bugs in 8.0 were removed specially driver conflict in Triple monitor when using Nvidia on-board graphics combined with PCI-e graphics. They also removed the wddm v1.2. In short, 8.1 is much better in rendering a Triple monitor without degrading PC performance. sad to say, I wasn’t able to benchmark the graphic performance because the windows experience index is already gone in w 8.1.
