AutoHotkey script to disable Windows key, Windows key + Tab and Alt + Tab key, useful to prevents accidentally pressing the keys when playing games, etc . . .

Disable Alt+Tab
;!Tab::Return
LAlt & Tab::Return

; Disable Windows Key + Tab
#Tab::Return

; Disable Left Windows Key
LWin::Return

; Disable Right Windows Key
;RWin::Return

The script above will disable Left Windows key and Left Alt + Tab key only, if you would like to disable both alt tab keys uncomment the following line:

;!Tab::Return

And to disable right Windows key uncomment the following line as well:

;RWin::Return

P.S: This script is used in the DisableWinKey utility that I created long time ago.
