Question

Can I simulate in C#/C++ code Control+Alt+Delete sequence in Vista?
When UAC enabled/disabled?
How it is done in XP?

Can you provide a code sample that works in Vista?

Answer 1

Existing code to simulate the Secure Attention Sequence (SAS), which most people refer to as control alt delete or ctrl-alt-del, no longer works in Windows Vista. It seems that Microsoft offers a library that exports a function called SimulateSAS(). It is not public and one is supposed to request it by sending a mail to [e-mail].

There is a similar library available with the following features:

• Works both with and without
  User Account Control (UAC)
• Supports current, console and
  any Terminal Server session
• Does not need a driver
• The calling application does not need
  to be signed or have a special
  manifest
• Supports multiple programming
  languages

Please note that this library is not free. Meanwhile you can contact [e-mail] if you are interested in it.
