How to use TeamViewer 14 Community as a service, so i don't need to login in first on the server, is that possible?
Assuming, you want the TeamViewer 14 full version starting as a service: Yes, that´s possible.
Just open your settings under Extras --> Options --> General --> Enable Start TeamViewer with Windows
And: You can always reach the community from within your TeamViewer application. You need to click on Help --> TeamViewer web help or TeamViewer Community
I hope the info helps you.
if Easy access is enabled you can also disable the random password in your TeamViewer settings.
You can read more about it here: All about passwords
Thanks and best, Esther
