Winaero WEI Tool

As you might be knowing, the Windows Experience Index (WEI) was removed from Windows 8.1. Microsoft left the WEI engine in the OS, but the UI was deleted from This PC/Computer properties. Recently, our good friends at IntoWindows reviewed the ChrisPC WEI tool. I looked at this tool but was disappointed that it didn't show the actual tests and assessments being done accurately. So I decided to code a better alternative myself with a nice looking, familiar UI. With WPF, it was a quite simple task.
So, here is my new freeware portable app, Winaero WEI Tool:

Latest version is, see the change log below.
It brings back the genuine Windows Experience Index and features the following abilities:
  • Calculation and re-calculation of assessments and scores.
  • The exact genuine Windows Experience Index look and feel.
  • The real, actual tests and assessments progress and status.
  • The ability to save a screenshot of your Windows Experience Index as a PNG file.
  • The ability to take a screenshot of your Windows Experience Index and upload it to ImgUr with one click!
  • The ability to save your WEI table to an HTML file!
  • Bonus: The background of your WEI score follows the window frame color for a cool appearance.

    You need to check the system locale for the proper decimal point. In some countries such as US where I am, it should be a dot instead of comma. For example: 5.9 instead of 5,9

    Just as in the regular windows tool, this does not work for OSs installed on to VHDs.

    In reply to Pepper, I am sure that we Americans are worldly enough to know that most European countries have a different notation then ours. We understand this, and can adapt.

    WEI quit working with Windows7.
    Can this be used with Windows7?

    You can use it, but Win7 has built-in WEI tool in the system properties.

    Doesn't work properly on my Nvidia Optimus laptop. Runs only on HD4000 even when I tried force it to run on the GTX 680M. Getting 4.x figures instead of 7.x - 8.x expected. 3D performance worse than desktop...

    It is not WEI tool issue.
    It is you OS issue.
    The tool is just GUI for the information reported by your OS.

    Should read: "The Windows Experience Index assesses key system components on a scale of 1.0 to 7.9" -- not 9.9. Thanks for this portable tool for assessing Windows 8 machines!

    Check if adapter is plugged if u run it on laptop/netbook because it can't be run on battery. To the autor: it'll be good if u put a message for this kind of situation. BTW, good and simple app/gui, thanks.

    Awesome thank you!

    FYI in addition to the typo pointed out about that 9.9 should be 7.9, also another typo is "Desktop Graphics" in the "Component" column should be "Gaming Graphics"

    Thanks, The Scores Go Up To At Least 8.9, My R290 Got 8.9 In Both Graphics Categories. I Know In Windows 7 The Scores Only Go Up To 7.9

    Many Thx for creating this useful simple tool. Very strange that Microsoft took it away...
    Anyway I'm happy to be the one who downloaded this tool as no #50.000 on this website... ;-)

    I'm not sure exactly why but this weblog is loading very slow for me. Is anyone else having this problem or is it a problem on my end? I'll check back later and see if the problem still exists. kgeeeebcedkaefea

    Doesn't run on my new HP Stream 11 laptop. The in progress screen flashes and returns to start screen with no values. I tried running the program as an administrator but it still fails to scan the computer. Any ideas?

    Same here. I was able to run it before. Now it just flashes for a second and then goes back to my previous test from March 2014.

    Then I run from command line to see the message cannot run while running on batteries. So if it is not working try to plugin.

    Typo in your Winaero WEI Tool -
    "The Windows Exprerience Index assesses key system components on a scale of 1.0 to 9.9"
    Should be Experience, not Exprerience

    Nice tool - thanks!

    So, does this tool only provides a WEI score or it does tweak your system based on the test like the way it was back in Windows 7?

    It's nice to be able to use the WEI tool on Windows 10, The only problem is that on all the 15 laptops I have tried it on it gives a score of 9.9 for the Desktop Graphics score, even on laptops from 2007 that I still have, otherwise it works great on all the other scores.

  46. twinlove69

    This is awesome, thank you so much for your time and effort!!!

    For some reason all of my machines are showing 9.9 on 3D graphics, I'm sure this isn't right, be even better if you could fix that, but all of the other scores appear to be accurate.

    Thanks a million!!! :-)
