easiest way to force quit on windows?

ctrl + alt + del is the backup when even ctrl + shift + esc doesn't bring task manager up, it's handled by windows itself so it gets through when the desktop is stuck. and if the screen goes black or frozen rather than one app, win + ctrl + shift + b restarts the graphics driver. you hear a beep and the screen flickers. nothing gets closed.

ctrl + shift + esc opens task manager straight away, pick the program and hit End task. that works even when the app is completely frozen, which alt + f4 often doesn't. on windows 11 you can also turn on End Task in the taskbar right-click menu (settings > system > for developers). handy if you do it a lot.
