Want to Disable the auto-startup of / Windows Startup of Teamviewer using registry ?

In case of unwanted remote control sessions , and have Teamviewer installed on many

Clients on Domains , I would like to be able to remove the " start teamviewer with windows " option via a policy using the registry editor , thus stopping teamviewer from automatically starting when Windows starts up. But... I do want if the client runs the application Teamviewer it will start but when the User restarts it will not auto-run. I cant jump from pc to pc to remove from startup.

Many Thanks
