Default Behavior
SSDP Discovery is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the SSDP Discovery service is started, it is running as NT AUTHORITY\LocalService in a shared process of svchost.exe along with other services. If SSDP Discovery fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the SSDPSRV service has failed to start due to the error.
Dependencies
SSDP Discovery cannot be started under any conditions, if the following services are disabled, deleted or working improperly:
While SSDP Discovery is stopped, the UPnP Device Host service cannot be launched.
