The design of Windows XP is such that, unless security is already compromised
in some other way, only the WinLogon process, a trusted system process, can receive
notification of this keystroke combination (because it is the first to register the keyboard hook).
This keystroke combination is thus a secure attention key. A user pressing Control-Alt-Delete
can be sure that it is the operating system (specifically the WinLogon process), rather than a
third party program, that is responding to the key combination, and that it is therefore safe to
enter a password. It was chosen as the secure attention key in Windows, thus no shortcut
is available.
