One of the things I hate about Windows is that there is no good way to kill frozen processes. Theoretically, you type Ctrl-Alt-Delete, wait for Task Manager to pop up, and kill the process. But in reality, the process doesn't always die immediately (it usually takes multiple tries and a very long time). GNU/Linux users don't have this problem. Here's how to end processes using the terminal, a few GUIs, and even a first person shooter.
