Free tools to forcefully terminate a full-screen application or game

The Task Manager had always been the popular tool to kill any application on Windows. Any program which doesn’t respond or closes the usual way (the X button) can be killed using the Task Manager. However, things are little different when it comes to full-screen applications, and games which always want to stay on top. Some such applications somehow disable the standard hotkeys that you can even switch to another application and forcefully close those applications. You might not be able to use shortcuts like Alt + TAB or Win + Tab and so on. If you are stuck with one such app or game, there are some free tools that can help you to forcefully terminate such full-screen application or game.

Windows 10 offers a good solution with Alt + Ctrl + Delete.  When you press this combination, it takes over the complete screen and then offers you lock, switch user, sign out and Task Manager. Try this first, and if it works, nothing like that – if not read on!

Tools to forcefully terminate a full-screen application or game

1] SuperF4

Available for both 32 and 64 bit, this application also offers keyboard shortcut- Ctrl+Alt+F4 which kills any application which is in the foreground. And, yes it’s portable. Once you download the application, keep it in place from where you will not delete it. Launch the program, and it stays quietly in the system tray waiting for those hotkeys to be pressed.

It also offers an xKill mode. When you press WIN + F4, it launches a skull icon in place of your mouse cursor. You can then drop it on any application you want to close.  In case you don’t want to kill it or on a wrong application, press ESC or escape on your keyboard, and it will exit.

Some games have anti-keylogger protection, which may prevent SuperF4 from working. To resolve this, enable the TimerCheck option to enable an alternate way to detect those keys. Right-click on the icon, and you can see options like elevate, elevate on start, and Timercheck. It is available here.

4] TaskKill Command Shortcut

If you know how to create keyboard shortcuts for applications, you can use the below-mentioned taskkill command to create a shortcut to kill any foreground applications. Basically, all these programs use this internally-

taskkill /f /fi "status eq not responding

Right-click on the desktop, and create a new shortcut. When selecting a program for the shortcut, you can add the command mentioned above, and save it. Now right click on the shortcut, and select properties. Switch to shortcut tab, and type combination of keys which will launch the program from anywhere.

Windows will add Ctrl + Alt to this, but you can change it to Ctrl + Shift + [Key] or  Ctrl + Shift + Alt + [Key].  Just make sure you are not using the same shortcut for any other program.

5] Process Assassin

You can also use a 3rd-party tool, like freeware Process Assassin. This tool enables the user to select a Not Responding application and terminate it immediately without calling any other external programs. There are options available too.

6] Task KillerThis tool offers a neat way to unload frozen applications, processes or services. It shows the tasks, windows, and services in a pop-up menu.

7] One Click App Killer: This tool doesn’t have an interface. Once you run it, your cursor gets transformed into a small round target. You basically have to click anywhere on the frozen application’s interface to terminate it instantly. This utility is a Windows clone of Xkill, from the Unix world.

NOTE: In Windows v1803 you can also terminate or close preinstalled system apps from Settings.

I am sure that there are many applications out there which can do this for you. However, we have only listed which are easy to use and works without a problem. Let us know if you are using something different.
