title: Disable Ctrl+Alt+Del on Windows 7
body: <p>I know this question has been asked a few times and in a few different ways.  However, across all the questions and answers, no one has been able to answer completely given my situation...</p>
  
  <p>I work on medical devices and they run Windows.  The application runs as the shell, users shouldn't be able to get behind the application, and ideally they wouldn't be able to do anything that indicates that the system is running Windows.  Access to the full keyboard is necessary so disabling, damaging or remapping keys is not a solution.  Given that, we need to disable SAS/CAD/Ctrl+Alt+Delete in specific; some others too, but those are easy with hooks.</p>
  
  <p>Up until recently we've been using Windows XP Embedded and could replace GINA, but we're about to switch to Windows 7 (technically Windows Embedded Standard 7; but in our case they're essentially the same) and GINA is no longer an option.  There must be a way to do this.</p>
  
  <p>Since I've seen comments about this on other questions: I do believe this belongs on Stack Overflow.  Replacing GINA is a programming question and there's no reason to assume this won't be too.  While I'm open to a non-programming solution, I doubt MS would make this kind of change available in the registry, etc.</p>
