Default Behavior

Windows Media Player Network Sharing Service is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Windows Media Player Network Sharing Service is started, it is running as NT AUTHORITY\NetworkService in its own process of wmpnetwk.exe. If Windows Media Player Network Sharing 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 WMPNetworkSvc service is not running because of the error.

Dependencies

Windows Media Player Network Sharing Service is unable to start, if the HTTP service is stopped or disabled.
