Windows only: Linux fans will instantly recognise Kill as a clone of the handy xkill utility, because both of them let you instantly kill off a process by clicking on one of its windows.Kill is an effective little application written in AutoHotKey. When you run the application it turns your regular mouse cursor into a cursor with a skull and crossbones, as seen in the screen shot to the left. If you left click on an application, Windows attempts to close it, as though you'd shut it down through normal methods and prompting you to save unsaved work. Holding down CTRL while you left click, and you kill the process behind the application, as though you had gone into the task manager and terminated the process. If you activate the Jolly Roger icon accidentally, pressing the ESC key returns your cursor to a less destructive clicker. For a tool with more diverse process killing options, like the ability to terminate based on the window name, check out Kill Tools, but for simple problem-enders, Kill is only 205k in size and is only loaded into the memory during actual use. Kill is freeware, Windows only.
