Presumably due to a Windows 10 update, headless access to my backup system no longer works. I have checked that Teamviewer is started as a service and is running, but the remote system hangs on the 'setting screen parameters' dialog, and eventually times-out.
I also note that setting the program to operate with admin privileges does not stop the "Allow this program to make changes" dialog from appearing, so adding it to the startup list is no good either.
Further, I note that Teamviewer no longer starts on boot-up on my remote system.
Does anyone else have these problems ?
