UnPlug n' Pray can check for the presence of the Universal Plug and Play (UPnP) service and enable and disable it as needed.

UnPlug n' Pray was initially designed for when this was a hot issue during the Windows XP days. The debate as to the threat back then went back and forth with the FBI even telling people to disable, then changing their mind. A lot of this may have been related to Microsoft patching the problem, so most people were safe after that.

If that wasn't enough, this debate has continued with many stories from reputable websites still reporting on the vulnerability recently. Is it true? We don't know. We're in the camp that believes anything that connects to the internet causes a security risk, and common sense applies. So, no, most people won't have a need for this app.

Universal Plug and Play (UPnP) is described best by WikiPedia as a set of networking protocols that permits networked devices, such as personal computers, printers, Internet gateways, Wi-Fi access points and mobile devices to seamlessly discover each other's presence on the network and establish functional network services for data sharing, communications, and entertainment. UPnP is intended primarily for residential networks without enterprise-class devices.

While this is a legacy app, techs and geeks may need to occasionally enable or disable UPnP making this free, portable, 22KB app still useful today. Those who are concerned can efficiently use this to disable the service and leave it until needed.
