New Post: Set-ActiveSetup and Remove-ActiveSetup: Per-user changes (as requested) Part2

Function Remove-ActiveSetup {
<#
.SYNOPSIS
    Remove an Active Setup entry in the registry
    
.DESCRIPTION
    Version: 0.5 - Author: CodePlex's That_annoying_guy - 2014 Sept 03 - BETA USE AT YOUR OWN RISK!!
    
    Active Setup is a built-in feature of Windows to handle per-user changes
    A registry key is created in HKLM and *as users login*, the user runs the "Stub" in the StubPath value and copies the Version value to HKCU in a matching Key
    If the Version value in HKLM is higher than the version value in HKCU, the StubPath is ran again when a user logs in.   
    
    -Removes Active Setup Key from HKLM. Does NOT touch Active Setup Keys in HKCU unless you use -purge
    -This is complimentary to Set-ActiveSetup
