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.

Not possible

Pepper | 17 Dec 13

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

Dave Johnson | 22 Dec 13

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

Dave Johnson | 22 Dec 13

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.

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.

Please change the , to a . It should show x.x not x,x for the results.

RonKirz | 01 Feb 14

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!

It doesn't work on my bay trail tablet.

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.

hi is it possible to rate the graphic card and not only the Intel HD Graphic ?

Anonymous | 28 May 14

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"

Anonymous | 29 May 14

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... ;-)

Smithk671 | 23 Jul 14

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?

nikolai | 19 Jan 15

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.

nikolai | 19 Jan 15

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.
