What is upnphost.dll?

The Universal Plug and Play (UPnP) implementation provides an architectural framework for creating self-configuring, self-describing devices and services. Because UPnP supports automatic discovery, devices managed by UPnP require no set up by users or network administrators. UPnP enables a device to dynamically join a network, obtain an IP address, and convey its capabilities upon request.

About upnphost.dll (from Microsoft)

“Universal Plug and Play (UPnP) is a distributed, open networking architecture that enhances peer-to-peer network connectivity for personal computers, wireless devices, and other intelligent appliances”
