Disable GUI autostart for Full Version (and mute audio)

flospi

We are about to rollout V14.2.2558 of TV Host and Full... On the test installations of the Full Version, we have two small issues for the mass rollout:

1) When a user logs on, the GUI of TV Full starts all the time and we do not find an option to disable it. I found a registry "Autostart_GUI", but whenever I set it to 0, it will reset to 1 again.

2) How can we mute the audio device by default? We use TV for transmission of the picture but we use Skype for Business for VoIP.
