    • Fabian, great script thanks!  Just a note script errors out on GPO's with colon (:) character in it - line 101:3 New-Item, which makes sense why because the path is not valid in Window FS.  Maybe put a check into your script for it?  If not just a quick statement.
    • Hi bpierce, take the new version, there is a fix for Unwanted characters. I hade the same issue at a customer side.
