Document Registry settings for Group Policy updates

I would like a list of registry setting that could SAFELY be changed via Group Policy on windows domain to change settings on the streamer.

In my case, I want to make sure that even if a user has local admin access, that on boot can:

1) Allow access (re-allow admin access)

2) Change the requirements of access (Password, Windows Cred, or Ask User)

Heck some of users even without Admin access, figured out how to disconnect/remove the streamer from the Splashtop management panel.  I even received an email from Splashtop telling me the streamer was either unlinked or removed.
