This Extension will deactivate the Windows logo keys and will stop the Start Menu from appearing as long as your game is running and has focus.
It is very useful if your game uses keyboard controls and your keys are close to the Windows key like Ctrl or the Z, X, C keys. The player might accidentally hit the Windows key and minimize the game breaking the immersion.
The Windows keys can also be activated back anytime, for example you might want to enable them if the player is using gamepad controls.
For security and better user experience, the Windows keys will be activated back if your game loses focus and when it ends (or if it ever crashes). It will also not disable Ctrl+Esc or any valid shortcuts that bring up the Start Menu as this is considered bad practice and degrades the user experience.
