Universal Plug and Play is a service on systems running Windows which helps configue networks and open ports for certain applications.
When the UPnP service is not functioning properly, you can run in to all kinds of issues and UPnP is a very small utility which can detect programs with the setup.
UPnP Test is very easy-to-use and contains no other functions other than to test services like the SSDP service, UPnPHost and the UPnP Framework Firewall Exception.
In total, there are 8 tests that UPnP performs and they can all be used in diagnosing issues with Universal Plug and Play.
UPnP Test is licensed as Freeware for Windows (32-bit and 64-bit) operating system / platform from network software without restrictions. UPnP Test 1.16 is available to all software users as a free download (Freeware).
