Resource filename?

[Scootermyth]

I need to find the resource file(s) that defines the standard blue background you see when XP displays the Welcome screen or the "Loading your settings screen" and also the logoff screen where it says "saving your settings". My theme is fairly dark and these screens with the light blue really clash with this. I would like to edit them with Reshack and replace the bitmaps if possible. Any help will be much appreciated.

If I remember it's msgina.dll (search for *gina*.dll ...)

Goodbye.

That's the one. Thank you.
