I am trying to prevent users 'escaping' using shortcut keys.
All OK for win 95 98 etc

 SystemParametersInfo(SPI_SETFASTTASKSWITCH,1,@Dummy,0);//Disable Alt-Tab
 SystemParametersInfo(SPI_SCREENSAVERRUNNING,1,@Dummy,0);//Disable
Ctrl-Alt-Del
 ShowWindow((FindWindowEx(0, 0, PChar('Shell_TrayWnd'), PChar(''))),
SW_HIDE);//hide taskbar

but with XP, one probably easy question:
 These work
   RegisterHotKey(Application.Handle,$BFFF,MOD_ALT,VK_TAB);// Disable
alt-tab
   RegisterHotKey(Application.Handle,$BFFE,MOD_ALT,VK_F4); // Disable Alt-F4

How do I disable Ctrl-Alt-Del ?  (3 key combination)

Regards
Graham
