Many people have used Task Manager to end a misbehaving process at some time or another. This functionality exists in Process Explorer as well, where it’s called Kill Process when you right-click a process. Process Explorer does one better than the stock Windows Task Manager by giving you the option to kill the entire process tree. Right-click a process, then click Kill Process Tree; or select Process > Kill Process Tree; or just highlight your process and hit Shift - Del.
Why would you want to kill a whole process tree? Sometimes when a process stalls out, it’s not the real culprit. Instead, one of the child processes it has spawned is the actual bad seed (we’re looking at you, Chrome). Even when the original process is the true villain of the story, killing it can sometimes leave orphan processes behind that can’t do anything without their parent, but which suck up resources anyway. Killing the process tree solves both problems at once.
