When you try to deploy a syspreped image of Windows 7 the setup process hangs at the regional settings page:
"Microsoft-Windows-International-Core" component is missing in the oobesystem configuration pass of the xml answer file specified in the advanced settings section of the Distribute Disk image task.
During oobesystem configuration pass, settings are applied to Windows before Windows Welcome starts. This pass is typically used to configure Windows Shell options, create user accounts, and specify language and locale settings. This configuration pass runs because by default the sysprep command is run with the /OOBE option within the imaging tasks of Deployment Solution.
