.NET Simulate Ctrl+Alt+Del Sendkeys

by

As of Windows Vista, you can use the SendSAS function.

Original answer, now superseded by the above

The function you need is called SimulateSAS. You need to e-mail [email protected] and ask for it. Microsoft don’t appear to document this, but just do a websearch for SimulateSAS and you’ll see what I mean.

Others have explained why it’s actually not a security issue to allow apps to trigger CTRL+ALT+DEL, but you certainly can’t do it with SendKeys.
