Hi! I'm currently having some trouble with my WINNT.SIF: ;SetupMgrTag [Data] AutoPartition=0 MsDosInitiated="0" UnattendedInstall="Yes" [Unattended] UnattendMode=FullUnattended OemSkipEula=Yes OemPreinstall=Yes TargetPath=\WINDOWS UnattendSwitch="yes" WaitForReboot="No" [GuiUnattended] AdminPassword=xxx EncryptedAdminPassword=Yes OEMSkipRegional=1 TimeZone=110 OemSkipWelcome=1 [UserData] ProductKey=xxx FullName="xxx" OrgName="xxx" ComputerName=xxx [Display] BitsPerPel=32 Xresolution=1024 YResolution=768 Vrefresh=100 [Identification] JoinWorkgroup=xxx [Shell] DefaultStartPanelOff=Yes CustomDefaultThemeFile="%WinDir%\Resources\Themes\Windows Classic.theme" [Networking] InstallDefaultComponents=Yes [GuiRunOnce] %systemdrive%\UNATTENDED\install.cmd As you see I've defined the classical Windows-theme as "CustomDefaultThemeFile". Everytime I am testing within a virtual-machine (VMware) I see the Royal-Blue-Design, which is the standard design of Windows Media Center Edition 2005, which I am using. Even tried to use DefaultThemesOff = Yes instead of CustomDefaultThemeFile, no success. Any ideas? Thanks in advance.
