The Block Level Backup Engine Service is a Win32 program that can be started by the Service Controller and that obeys the service control protocol. In Windows 8 it will not be started until the user starts it. When the Block Level Backup Engine Service is started, it runs as localSystem in its own process of wbengine.exe. If Block Level Backup Engine Service fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the wbengine service hasn't been started.
