Source Code (C#)
Description:
This application suppresses windows key presses, it can be turned on and off from the system tray, the icon will indicated if its active or not.
This application is useful when playing full screen games, many of which can be made to crash, or lose focus at the press of the windows key.

Is it possible to use WinKeyKill in command-line? Thanks!
@Claudio I’m sorry currently it is not able to be used from the commandline, sadly this application source is currently MIA, if I can find the source I will see if I can make the adjustment.
