Greetings,
I’m currently using an HP G2 with Win11. I select full screen when I fly and primarily use the mouse. The problem that I seem to be having is that Fullscreen is more borderless than full screen. When it pops up it really messes up the flight and ability to do just about anything until I alt-tab back to the flight. Does anyone know how to disable the “Let’s connect with Teams!” flyout in the middle of the task bar and the news flyout on the left?
Open Teams and change the settings. Simple 
I uninstalled Teams. It’s nagware.
