Don't even try, there is (or was a few year ago) an SDK you could apply for from Microsoft. But I doubt they even allow that these days. Why would you want to given the security implications?

Ah now you might in luck there, I believe there is some banner style text that you can change and it will show that with the login.

e.g. http://www.pctools.com/guides/registry/detail/22/

Thank you for this advice, but with this tool i can only show Text in a popup. I need something which can play a video for example or other streams(picture as stream etc.). Is there a possibility to manipulate the logon screen background, so that the background is a stream?

I believe you can change the background too, but I would think it would be very restricted. I believe it loads the background only the once and displays it so I doubt streaming would be the answer, possibly (if unlikely) a GIF but I doubt that would be of any use. Do you mind answering what this is for? I.e. why not do it when they login?

My program is a Windows Form which recieve a stream. This can be a video or picture which contains informations. This video or picture have to be seen before login. The user also is not allowed to close the stream until the video has finished. When it is a picture the picture is shown for a few seconds. After this the user can login.

It's the "has to be seen before login" that puzzles me. Why does someone, unathenticated, need to see something before they login?

The program is for people(me too )who want to tune their logon screen. For example: A Virus symbol, or when i want to remind me on something important i can show it before logon so i can't ignore it.

Well I think you're stuck with static changes for the loging, but you can force your program to run as soon as they login to solve the "must do" part.

Well, thank you for youre help. Do you know something about api? I've heard about the "GetCurrentDesktop()" Function. With another Function you can create youre own window. As far as i know the logon screen is a stand alone desktop, is it?
