Create a theme which changes windows logon Screen

Hi,
I want to that "how to create a theme that changes windows logon screen"
I know that one can manually change windows logon screen by making a new folder named info and again making a new folder in the info folder named backgrounds and then by putting a picture in backgrounds folder and name it to backgroundDefault but I want to save this image in a .themepack so that when i install that .themepack in a new machine it automatically changes the windows logon screen.

Hope that you would understood the problem,if yes please help

Thanks

But I have seen a few themes especially "OEM brander theme" which changes every thing but through GUI program.Don't you any thing like that?

Brink thanks for your assistance.Hope that one would post the solution.
However this is a microsoft msdn link below,which says there logon background information is there in the .theme pack

Theme File Format (Windows)

come on guys, does anyone know how to make a theme file that changes the windows login background

Please?

Thank you in advance

Its just not possible to do using a theme file as its not in any way involved with changing a theme. The only way would be to create an installer for the theme and include a .bat file to run during the installation to change the logon screen. Far to much work when this Log On Screen - Change can be done in seconds anyway.

Would you please tell me or give me link that gives us the knowledge for creating a batch file for theme installer and obviously the installer as well?

Each and every suggestion would be highly appreciated.

Thanks.

Add in the top line the following:
[Theme]
; Windows 7 - IDS_THEME_DISPLAYNAME_AERO
DisplayName=*THEME NAME*
SetLogonBackground=1
BrandImage=\Path\To\Logon\Image.png

Must be .png

You're very much welcome.

I tried the method and in the theme area it does recognize the logon screen but the screen does not change, what should I do?
i have up loaded the screenshot of how the modified theme looks in the personalise page.
