4.2.11 UPnP 
UPnP (Universal Plug and Play) allows Windows based systems to configure the device for various Internet applications 
automatically. UPnP devices can automatically discover the services from other registered UPnP devices on the network. 
If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time communications, like instant 
messaging or remote assistance (a feature in Windows XP), you should enable UPnP. 
 
 
Enable UPnP: Check/uncheck to enable/disable  the UPnP feature.
