When a program freezes, you can usually kill the process through the Windows Task Manager. Sometimes, however, you might find that the Task Manager cannot be opened when a program freezes. This is where SuperF4 comes very handy. It force the stubborn program to close.
SuperF4, in most cases, forces a program to close when it is freezing the system to the point where Windows Task Manager cannot be opened. Using the application is just as easy as pressing Ctrl+Alt+F4 when you find a freezing program. The force close feature is disabled by default, to run it you need to enable it first. The SuperF4 tray icon can be hidden if you want to.
