F1 Function Key Tries to open the 'help' window in any program, and if that program doesn't have a 'help' window/center, it causes the window's screen to flicker. This is very annoying in Notepad++ or in games that I play and use the key. I don't want to rebind the key because some of these games do not allow me to change the controls.


Disable the F1 key on the Registry Editor:

Windows Registry Editor Version 5.00

;Disables F1 key - Help and Support - in Windows 10
