I am playing Assassin's Creed on Windows 7. After I launch the game, suppose I get a pop-up (like Windows Update). Now the game is stuck in windowed mode, and no way to get it back to full screen.
Is there any way to do go back to full screen without restarting the game, or possibly avoid these popups to begin with?


-fullscreen. That should work to my knowledge. – jeffreylin_ Feb 8 at 23:44
