Nitin Bhat the WMI PM recently pointed HERE to answer the question, how do know what OS SKU a machine is running?

You can run the expression $((gwmi win32_operatingsystem).OperatingSystemSKU) to the the value and then look it up on that table.

I decided to turn it into a script you can use.  It is rock-simple but it saves you the typing and there's some value in that.  I've included it below and attached it as well.

  • Please add 1 and 1 and type the answer here:
  • Post
  • Useful script, just note that it only works on Vista and WS2008.

  • To DEP or not to DEP – A good post on DEP from the Performance Team Windows XP era draws to a close –

  • Nice, very useful.  Still learning PowerShell, just curious why he used the outer parenthesis.  Why "$((gwmi win32_operatingsystem).OperatingSystemSKU)" instead of "$(gwmi win32_operatingsystem).OperatingSystemSKU"

  • Here's an improved version taking the computer name and version number into account:

    #Requires -Version 1

    # GetOSSku.ps1

    # Get OS SKU

    function global:Get-OSSku


    param([string] $computerName)

    if(($computerName -eq $null) -or ($computerName -eq ""))


    $computerName = "localhost"



    "Computer:`t" + $computerName.ToUpper()

    $wmi = $(gwmi Win32_OperatingSystem -computerName $computerName)

    $sku = $wmi.OperatingSystemSKU

    "Version:`t" + $wmi.Version

    "SKU:`t`t" + $(
