The most powerful web browser Internet Explorer enables users to scratch the screen in full screen mode. It could just be invoked by pressing F11 key on the keyboard. The process is called Kiosk mode. Being a user you can also perform it by entering iexplore -k in the Start menu’s Run dialog box. Alt-F4 or Ctrl-W would close the Kiosk-mode window .Administrators lock down these key combinations using restrictions in the Registry entries.
