WillShowUI specifies in what circumstances to display the user interface (UI) for disk configuration. Settings in DiskConfiguration are processed before the UI is displayed, but setting this value to Always or OnError gives notification of success or failure.



Specifies that the UI is always displayed.


Specifies that the UI is displayed only if an error occurs, even for catastrophic, non-recoverable errors. This is the default value.


Specifies that the UI is never displayed.

WillShowUI only prevents Windows Setup UI pages from being displayed. If a critical error occurs, an error message might be displayed. To avoid displaying the error message, you can use the ErrorHandler.cmd file to automatically run a script to handle the error. For more information about ErrorHandler.cmd, see the OEM Preinstallation Kit (OPK) User's Guide (Opk.chm) or the Windows Automated Installation Kit (AIK) User's Guide (Waik.chm).
