SSDP Discovery

Default Description:

Discovers networked devices and services that use the SSDP discovery protocol, such as UPnP devices. Also announces SSDP devices and services running on the local computer. If this service is stopped, SSDP-based devices will not be discovered. If this service is disabled, any services that explicitly depend on it will fail to start.

Additional Information:

SSDP service is required to see networked resources (Network Discovery) in the "Network" display pane.
