Get-OSSku.ps1
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.
