I'm developing one kiosk software, to run over Windows 7.

I need to block key sequences like alt + tab, alt + F4 etc. How can I block it?

Remove the keys from the keyboard :) – John T Feb 7 '11 at 0:01

Autohotkey can do this in a single line:


It's useful for blocking all of the common nasty key combinations you wouldn't want used on a kiosk, such as Alt+F4, Ctrl-W (depending on browser used), F11, and so on.

How to use this? – metal gear solid Oct 7 '11 at 3:49
@metalgearsolid - Get AutoHotkey, create a new script, copy-and-paste that line in, and run the script. – Unsigned Dec 18 '11 at 0:11

I would suggest reviewing this:

(Registry entry should do the trick).

Also, I would look into replacing explorer as the default shell app. Then you'll have more control over what people run.

That registry entry is absent and does not work in Windows 7 AFAIK. – John T Feb 7 '11 at 0:38
