Is it possible to configurate the TeamViewer so the user can't performs the shutdown, reboot, lock user, log off etc. via remote control?
I really doubt it. I don't think the computer can tell the difference between input from a user sitting at the computer, and from someone connecting through Teamviewer. You'd probably need to disable it completely on the computer, and require a password to re-enable those controls.
my biggest issue was that the remote user would exit the Teamviewer program without my knowledge, thus I could not remote in when I needed to. TO solve problem, started teamviewer on remote, clicked on extras and then options. Clicked on advanced, and then "show advanced options" Scrolled down and put a check mark in "disable teamviewer shutdown" Clicked ok. Now they cant close teamviewer.
Another trick is to hide tray icons. this requires using the regedit command. see the following.
Follow the procedure given below to implement the registry edit to hide all the system tray icons in your sidebar.
Hope this helps
