Default Behavior
Interactive Services Detection shows message boxes when it is necessary. In Windows 7 it won't be started if the user doesn't start it. If Interactive Services Detection fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the UI0Detect service is not running because of the error.
