I highly suggest people turn this service off as you are putting yourself and others at risk.(internet search ="Universal Plug and Play threat")
I disable UPnP by going to Start>RUN> typing = MSCONFIG
and going to the Services tab, you can uncheck the box that says Universal Plug and Play this does the same thing as working through control panel mentioned above.
Disabling will not limit your ability to access network components, it will force the user to manually browse for the network printer, etc. instead of the machine automatically adding it which in my opinion is anoying anyways as I had 30 unwanted printers at one point because of this.
