The Windows Update service runs as LocalSystem in a shared process. It shares the executable file with other services. If the Windows Update fails to load or initialize, the error is recorded into the Event Log. Windows 7 startup should proceed, but a message box is displayed informing you that the wuauserv service has failed to start.
Dependencies
Windows Update will not start, if the Remote Procedure Call (RPC) service is stopped or disabled.
