sandkorn1978, you got it other way around. This entry tells Windows to change to default or keep old one Logon background. You CAN NOT install a new Logon background simply by applying a theme file (Only if you will patch default background beforehand).

that's what I've already done for my Windows, so I know this way very good...
I couldn't find the themes from M$-page... Someone told that there are themes with that function, but wasn't able to tell wich ones that were...
I'm not even sure if it's in the .theme-file, so it could be any way to get it changed...
But I think it'll get changed by one click with the complete theme...
I'll stay on it, so if I get a clue, i'll post it here
