Consider the following scenario:

• You use the Microsoft-Windows-Shell-Setup component to install Windows Vista on a computer.
• The version of Windows Vista that you want to install does not include the Media Center component.
• In an unattended XML file, you specify use of the ShowMediaCenter child element to hide the Media Center component in the WindowsFeatures element.

In this scenario, the installation of Windows Vista fails. Additionally, you receive the following error message:

Windows could not parse or process unattend answer file [C:\windows\Panther\unattend.xml] for pass [oobesystem]. The settings specified in the answer file cannot be applied. The error was detected while processing settings for component [Microsoft - Windows - Shell -Setup]
