Disable Universal Plug and Play Services (Windows XP) Popular

Windows XP includes support for Universal Plug and Play (UnPnP) which allows UnPnP devices to be connected over a network. There are currently limited UnPnP devices available and due to a recent security flaw it may be advisable to disable these services.

This tweak can be easily applied using WinGuides Tweak Manager.
