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.
Disable Universal Plug and Play Device Host
Open your registry and find the key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\upnphost]. Set the value of “Start” to “4″ to disable the service, or “3″ to enable it.
Disable UnPnP Discovery Service
Open your registry and find the key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SSDPSRV]. Set the value of “Start” to “4″ to disable the service, or “3″ to enable it.
Restart Windows for the change to take effect.
System Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\upnphost]
Value Name: Start
Data Type: REG_DWORD (DWORD Value)
Value Data: (3 = enabled, 4 = disabled)
