Default Behavior

Block Level Backup Engine Service is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Block Level Backup Engine Service is started, it is running as localSystem in its own process of wbengine.exe. If Block Level Backup Engine Service 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 wbengine service is not running because of the error.
