First things first, set your Windows desktop to the appearance you desire, including Icons, sounds, screensaver, cursor and wallpaper etc. Then Open up the Display Control Panel, and select the Themes tab and save theme to desired name you like. For ex i save it as Jatin.theme Then u need to create $OEM$\$$\Resoureces\Theme and copy ur theme folder into it. Be aware to keep OEM Preinstall YES and then add this line to winnt.sif file created by nlite. [shell] CustomDefaultThemeFile = "%WinDir%\Resources\Themes\Jatin.theme"
