The quickest way to switch to full-screen mode on Microsoft Windows is by pressing the F11 key on your keyboard. This will work for the majority of browsers and apps. When it comes to videos or media players, the usual way is by clicking the full-screen icon(or double-clicking on the video). In games, full screen is most often a display setting that can be toggled on/off. To maximize a window, you can either click the square icon located in the upper-right corner or press the Windows key + Up Arrow. When you want to go out of full screen, the combination will be either F11 or Esc, depending on the program.
