I would like to make all three of these screens the same.
I could do this in the XP-days. Then I used a program called IrfanView. Then you/I made a .jpg picture as a background, Windows would convert it to a .bmp file.
I edited the registers in XP that made the location of that file "Irfanview_Wallpaper.bmp" as the startup and shutdown screen. That way your desktop wallpaper came up way sooner than normal, and stayed up until shutdown.
But it seems Windows-7 doesn't save backgrounds to a .bmp any more, to use it.
This program "Windows 7 Logon Background Changer" will change the startup and shutdown screen, regardless of the size of the picture. But I would like to be able to point it to a default location where the present wallpaper is located.
I'm guessing I'm out of luck in Windows-7, unless someone knows more on this.....?
