How To Get Windows Experience Index (WEI) Score In Windows 8.1

Windows Experience Index (WEI), one of the hundreds of features introduced with Windows Vista, is designed to help you better understand your computer’s capabilities. It scans your computer hardware and assigns it a score after running a number of tests. These ratings help users in purchasing software and games.

Windows Experience Index in Windows 8.1

For instance, a base score of 5.2 means that the PC will run an application or a game if the WEI score of the game or application is less than, or equal to 5.2.

In Vista, Windows 7 and Windows 8, Windows Experience Index could be accessed by right-clicking on Computer icon and then clicking Properties. However, in Windows 8.1 Microsoft has partially dropped this feature and it doesn’t appear in Computer Properties.

Even though most users don’t refer to the base score of WEI before installing software and hence will not miss this feature in Windows 8.1, some users who refer to WEI score might want know how to get back the feature or at least how to check Windows Experience Index ratings in Windows 8.1.

As we mentioned already, there is no perfect workaround to add WEI to Computer Properties. However, since Microsoft hasn’t completely removed this feature from Windows 8.1, there is a way to check WEI score.

    DataStore folder is EMPTY.
    Windows 7 Ultimate x64, ASRock Z170 Extreme 4, Intel 6th Generation i5-6500 Skylake LGA 1151
    When installing Intel 530 graphics Driver a window says automatically run WinSat and enable Windows Aero.
    Aero is working.
    Has this newest LGA 1151, Skylake, Z170 platform done away with WEI?

    Thanks, Robert

    None of what Tyran posted works for my 8.1. Ram & CPU is there inherently, but no WEI is shown.
    ‘C:\WINDOWS\system32>winsat formal’ shows lots of output, but the only thing in it that resembles
    a WEI like number is in the last 3 lines…

    > Video Memory Throughput 3416.99 MB/s
    > Dshow Video Encode Time 2.53239 s
    > Media Foundation Decode Time 0.10644 s
    > Disk Sequential 64.0 Read 480.45 MB/s 8.1
    > Disk Random 16.0 Read 227.45 MB/s 7.9
    > Total Run Time 00:02:15.77

    Does this mean my WEI is 8.1 or 7.9 or neither? Did I miss something?

  3. tyran says

    in windows 8 and 8.1 you can open file explorer and right click on computer then properties then you should be able to get into the windows experience index

    or put this into file explorer

    ////// Control Panel\All Control Panel Items\Performance Information and Tools //////

    another way is go to control panel (ensure the control panel is in category view)

    go to system and security
    then under system you will see, view amount of ram and processor speed, click it
    then in the same panel as your processor information just above where it states what your processor is it will say windows experience index in blue writing click that and welcome to the (WEI) scores

  4. alamo says

    i deleted all the “formal assessment xml” file unknowingly
    now it says error “could not build a topology to decode the inbuilt file”
    i tried both “winsat formal” and “winsat formal -restart” but now xml files are no longer generated
    please help

  5. George Caldwell says

    I don’t get it man. I always get a score of 5.9 because of my hard drive always getting 5.9 , My GPU a R9 270 gets 8.4 and the old i5 750 quad cpu gets 7.4, and the 8GB Ripjaw 1600 DDR3 gets 7.7 , But yet my HDD gets. I don’t understand anyway why the speed of a HDD makes any difference in gaming. A old sata 7200 RPM is more than sufficient for any game with any gaming rig. Even the older 5400 RPM HDD is fine for gaming. So wtx?? I understand the windows experience score is pointless anyway. But still who rates a computers gaming performance on the type of hard drive? That’s ridiculous.

  6. kentt says

    awesome, but have a question, i notice it cant detect my second graphics card GTX 870M , which is im pretty much sure should score more than 7.6… but instead it only rates my onboard GPU intel with 5.6.. any ideas how to make the gtx 870m detectable. i turned it on in my nvidia ctrl panel btw..

  7. Nick Paling says

    “Winsat format -restart” should probably be
    “Winsat formal -restart”

    Otherwise great page.

  8. Pieter says

    Thanks for the work around. I am upgrading my hardware and wanted a simple tool to tell me what strengths, if any, I have gained. Nice work.

  9. Mike says

    I found a soft that you can easily use to rate the computer and view all WEI score. It’s called ChrisPC Win Experience Index.

  10. Robb Ferster says

    worked as explained, thank you!
    n to the person who said we don’t need it or its crap, well sorry to contradict its a worth while tool when advising customers on what type of computer / laptop they want to fill their needs!

  11. anon says

    wow dude. google.. got me exactly what i was cooking for and it took me to u with not only the bad news that this feature was gone.. i know who cares we don’t need it but this guy worked around it.. thanks bud for the work 8)

  12. BKize says

    Thanks for this article. I didn’t find any other coverage of this Windows 8.1 topic.

    Please note that there’s a typo above: “Winsat format -restart” should be “Winsat formal -restart”

  13. Michael McShane says

    Running Winsat on win 8.1 rtm works until it gets to the direct3d tests and then fails with a “A problem caused the program to stop working correctly…”
