What is SuperF4?

SuperF4 kills the foreground program when you press Ctrl+Alt+F4. This is different from when you press Alt+F4. When you press Alt+F4, the program can refuse to quit. Windows only asks the program to quit, and lets it decide for itself what to do.

You can also kill a program by pressing Win+F4 and then clicking the window with your mouse cursor. You can press escape or the right mouse button to exit this mode without killing a program.

Some games have anti-keylogger protection, which may prevent SuperF4 from working (it can't detect when you press Ctrl+Alt+F4). You can enable TimerCheck to use an alternate detection method.

2019-02-16 - SuperF4 v1.4 released

Released 1.4.

I apologize for my tardiness. I use Windows less and less every year, and I must confess that I have not even been running my own programs when I do. I hope this release makes up for it somewhat.

2015-08-23 - SuperF4 v1.3 released

Released 1.3.

The installer now defaults to install to the %APPDATA% directory, so it won’t ask for administrator privileges when you start it. If you want to install to Program Files, right-click the installer and select Run as administrator.

Due to this change in the installer, I recommend that you uninstall and install from scratch if you are upgrading from a previous version!

Lastly, I want to thank everyone who have donated. All support is greatly appreciated!
