The regedit function doesn't really run as a user even though it's set to in the advanced options of the function. It really runs as a system user, so it doesn't see the user enviroment as it should.

I tried to have it grab the ${USERPROFILE} and it put "c:\windows\system32\config\systemprofile" for a path. I tried to have it grab ${USERNAME} and it grabbed the computername instead.

I've opened a ticket SR # 10450736061 and will follow-up here.
