SuperF4 1.1 is a Mouse & Keyboard product from code.google.com, get 4 Stars SoftSea Rating, SuperF4 enables you to kill the current foreground process by simply pressing Ctrl+Alt+F4 on your keyboard. Unlike the standard Alt+F4 command which only attempts to terminate the process but does not force it to close, SuperF4 will impactfully kill it, no questions asked (unsaved data is lost though). The software can come very convenient if an software is freezing your system to the point where you can`t even get the Windows TaskManager to open, leaving you with no options other than to reboot your system. SuperF4 will take care of the problem in most cases.
What SuperF4 basically does, is kill the process of the foreground window when you press Ctrl+Alt+F4. You might think, doesn't Alt+F4 do this Well, it's a bit different. When you press Alt+F4, the software can refuse to quit. Windows essentially only asks the software to quit, and lets it decide for itself what to do (almost always it behaves just as if you would have pressed the in the upper-right corner).
You can also kill a process by pressing Win+F4 and then clicking the window with your mouse. You can press escape or the right mouse button to exit this mode without killing a program.
Why
You might have encountered a game that hung because of some stupid bug, then your computer gets all slow and you just can't get out of the game since it's fullscreen and nothing happens when you press Ctrl+Alt+Del to bring up the task manager. You eventually give up and reboot the computer by pressing the power button. :(
This have happened to me quite a few times and I got tired of it, so I made SuperF4. Now I can just press Ctrl+Alt+F4 and get back to the desktop within a few seconds. :)
More
SuperF4 should be able to kill all kinds of processes, whether they are hung or not. Beware though, SuperF4 impactfully kills the software and doesn't give it a chance to save unsaved work.
When started, you can enable or disable SuperF4 by clicking the tray icon. No other configuration except autostart exists.
