You can't intercept Ctrl+Alt+Del, for a very good reason. If you could,
Trojans could use the same technique to masquerade as the Windows log-in and
capture your user name and password.

The spammers and script-kiddies have succeeded in making it impossible for
me to use a real e-mail address in public newsgroups. E-mail replies to
this post will be deleted without being read. Any e-mail claiming to be
from brenreyn at indigo dot ie that is not digitally signed by me with a
GlobalSign digital certificate is a forgery and should be deleted without
being read. Follow-up questions should in general be posted to the
newsgroup, but if you have a good reason to send me e-mail, you'll find
a useable e-mail address at the URL above.
