OK, I found a serious problem with TV, and unless I buy the product, I don't get to contact support, what a load of **bleep**, and there is no actual support of the product for free users except this forum , anyway, this is what I found, if TV is used as a master to remote to a slave machine, it is not needed to run when windows starts, but it does, regardless of settings, if I uncheck the option to 'start with windows' the TV service is still there and running, even after a total shut down and restart of the PC, or even if I completely remove it using Revo Uninstaller, then reboot the computer, and re-install TV with the option as a standalone install, the service still gets installed and run, the only way to stop TV from running in the background, is to first make sure the 'Start with windows' is definitely unchecked, this can be checked by closing TV, then re-open TV and look at that setting, then to remove the service use an elevated command prompt and type:-
sc delete teamviewer
This is the only way to stop TV from running as a service. As I mentioned earlier unless you want to control the master machine remotely there's no need for TV to be running at all, slave machine? yes but not the machine that's going to remote access the other machines.
