Do you have the ClipboardFusion icon hidden or visible in the system tray? That's strange that the notifications setting keeps getting disabled, we haven't seen that issue before in Windows 10.

Happens to me, too. I have ClipboardFusion icon set to be shown at all times in system tray.
However Windows turns off its notifications from time to time. Same thing happened to Java Update Checker.
Have you guys figured out how to solve this problem, perhaps?
