I'm having problems with heavy CPU load on some PC - i.e. right after reboot it already takes 40-50%, and continues that way.

According to other posts, this could be related to hardware accelleration, as described in this topic: "High CPU usage on remote side of TeamViewer Connection"
However, this post has a note : "Note: These instructions only apply to Windows 8.x and older. Windows 10 does not provide the ability to disable hardware acceleration this way."
Then the question is, what can be done on a Windows 10 (1703) and TeamViewer 12.0.83369 to remedy?
