MIMWAL Can run PowerShell 3.0 and beyond without PSRemoting or Start-Process!
I just discovered that a colleague had several years prior managed to get MIMWAL PowerShell Activity to run Get-ADUser and other commandlets from the Active Directory Module (which requires PowerShell 3.0 or later) without using PowerShell Remoting or starting a new Process with Start-Process.

So if you aren’t using SSPR through MIM this might be an option for you!
