Themes .default settings

[EagleWing]

What I would like to know is if there is a way to change the default color settings in vista's aero.theme, such as desktop background color from black to blue or whatever. Actually I know how to do what I just described. The issue I'm having is that I save my edited aero.theme as My favorite theme and then later rename it as aero.theme and copy it and Windows classic as well as aero.msstyle file to the %systemdrive%\windows\resources\themes folder inside my mounted install.wim file. I then set it as the default theme in my autounattend answer file. But when I install my modded version of Vista Ultimate SP2 it reverts right back to the default colors. So, does anyone have a clue as to what I need to do? I am assuming that there may be some sort of system file protection I may need to disable. Is my assumption correct?
