Alt+F4

The mean way to make a newbie quit on windows computers

Newbie: how do i ____?
Dick: Alt+F4
Newbie *quits and is discouraged to play and leaves which slowly makes the community only pros making new people steer away and eventually killing the game as a marketable object*

Alt+F4

The biggest life changing function in Windows. Used to close Chrome in Computer Science classes. It is also used in online classes to mute the volume of teacher. Thanks Microsoft for this stuff

My teacher asked me to volume down and I told him to press Alt+F4. I escaped from an online class

10 Year old: Hey how do you run fast?
xxmLGpro69x: Press and hold ALT + F4
10 Year old has left the game.
