About SuperF4
SuperF4 is a Windows-only application that kills the foreground program when you press Ctrl+Alt+F4. Unlike Alt+F4, which asks a program to quit and allows it to refuse, SuperF4 forces the program to close. It also offers a second method where you press Win+F4 and then click a window with the mouse cursor.
The site provides downloads for version 1.4 in portable 64-bit and 32-bit builds, along with a changelog and release news. It includes support guidance, such as checking GitHub issues before reporting bugs, and notes that TimerCheck can be enabled if games with anti-keylogger protection block the shortcut. The software is licensed under GNU GPL v3 with source code available on GitHub.
SuperF4 suits Windows users who need to close programs that do not quit with Alt+F4. You can exit the Win+F4 selection mode with Escape or the right mouse button.
