Windows Experience Index for Windows 8.1

Version 11


    The “Windows Experience Index” (WEI) was introduced in Windows Vista, and was available in Windows 7 and Windows 8.


    It provided an assessment of the hardware (CPU, Memory, Graphics, Gaming Graphics, and Disk) of the PC, and displayed the performance results.  Some users liked the assessment, as it provided an indication of where their PC ranked in the various categories and, using this information, where improvements might be made.  For example, if your onboard graphics rating was low, you might decide to purchase a higher performing graphics card.  Then, re-running the assessment would show the improvement gain.


    However, in Windows 8.1, the WEI is gone.  Well, not really.  All of the underlying programs and ability to generate the assessment are there.  The problem is that the ability to invoke the assessment from the properties page of your system (Control Panel\All Control Panel Items\System) has been removed for reasons unknown.  Perhaps the hardware had reached a level of performance that rendered the WEI data unnecessary or unreliable.


    So, you have purchased a new PC or laptop, or updated memory or CPU, or even added a new video card or SSD, and would like to see the WEI data, it Is still possible to run the WEI programs and view the data.  The data is not presented in the graphical interface, but rather text.


    To create and display this WEI data, create a text file with Notepad (WEI.TXT, for example), on the desktop of your Windows 8.1 machine.  In this text file, copy and paste the following commands, exactly as they appear:


    @echo off

    echo Windows Experience Index

    winsat formal –restart

    powershell Get-WmiObject -Class Win32_WinSAT




    Now, save and close the text file.  Rename WEI.TXT file to WEI.BAT.  Once this is done, right-click on WEI.BAT and select “Run as Administrator”.  Then, sit back and watch all of the various assessments being run.  This can take several minutes, just as it did under Windows Vista, 7, and 8.  Once completed, you will see the following output in the Command Prompt window:


    __GENUS               : 2

    __CLASS               : Win32_WinSAT

    __SUPERCLASS          :

    __DYNASTY             : Win32_WinSAT

    __RELPATH             : Win32_WinSAT.TimeTaken="MostRecentAssessment"

    __PROPERTY_COUNT      : 8

    __DERIVATION          : {}

    __SERVER              : XYZZY

    __NAMESPACE           : root\cimv2

    __PATH                : ...

    CPUScore              : 8.3

    D3DScore              : 5.7

    DiskScore             : 8.1

    GraphicsScore         : 5.8

    MemoryScore           : 8.3

    TimeTaken             : MostRecentAssessment

    WinSATAssessmentState : 1

    WinSPRLevel           : 5.7

    PSComputerName        : XYZZY


    Ok, now we have the results from running WEI.  Not as pretty as the GUI display you were accustomed to, eh?   The output we want, in the order that we were previously familiar with, appear below:


    CPUScore              : 8.3   Processor:          Calculations per second

    MemoryScore           : 8.3   Memory (RAM):       Memory operations per second

    GraphicsScore         : 5.8   Graphics:           Desktop performance for Windows Aero

    D3DScore              : 5.7   Gaming Graphics:    3D business and gaming graphics performance

    DiskScore             : 8.1   Primary hard disk:  Disk data transfer rate

    WinSPRLevel           : 5.7   Overall base score: Determined by lowest subscore


    You can see that my weakness is the graphics.  In this example, I could benefit from adding a higher performance graphics card, which I plan to do.


    There is much functionality in WinSAT program.  To learn more, open a Command Prompt (Admin) and enter WinSAT /? to display all of the options and switches available.


    Now, go test the performance increase from your newly upgraded CPU or Intel SSD!
