The program can verify whether the operating system provides support for the UPnP service and allows you to check if the Simple Service Discovery Protocol (SSDP) and the UPnPHost services are running. The interface is compact and simple, comprising only two panels: one that displays the test type and its short description and the other for viewing which of the tests passed and which failed. One advantage is that the application does not require installation, so your system registry is not affected in any way.
Before you get your hopes up, you should know that this tool does not solve the detected problems, but only performs a series of tests to identify the possible causes. This simple program is designed to help you identify the issues that prevent the UPnP protocol from functioning correctly. That is where the UPnP Test application comes in. If you are experiencing problems with the Universal Plug and Play service, your computer might not be able to automatically detect the presence of other networked devices, such as PCs, printers, Internet access points and so on.
