Get the bar off during games?

I'm currently playing a game on the laptop, but the taskbar and is still displayed. I don't know how I can get it away. I have already tried F11.

You have to play in full screen mode.

Otherwise you can also hide the taskbar, go to the taskbar setting and activate Hide taskbar there.

Or the taskbar is fixed… You can see this if you move the mouse to the taskbar and take the right mouse button…
