Hello everybody,

I would like to make application for windows based system for user authentication. Does anybody have some experiences with this? I am planning authenticate users via face recognition, but I am curious how to start that app before user loggs on to system.

The Windows application you can start up before any user is logged in is a Windows Service which is set up for auto start (you can see this option if you start the "Services" Control Panel applet). But it would not make any sense, because this could not be the UI application.

The only thing you can do to intercept the login is creation of a custom credential provider. Please see:

But first of all, please see my comment to the question and think about it.

I am asking because there exists face recognition application for authentication. I wanna do the same.

Thanks for your answer

Certainly. My notebook came with one. But this is not a software development question. Find one and install it if you want.
