TAP driver / identified vs unidentified networks

Question

Hi.  I'm running Win7 build 7000, trying to get both my OpenVPN connection and my coLinux connection (TAP-Win32 v9.0.0.4 and 8.0.0.4 respectively) to be identified as Home networks. 
Currently they each show as "Unidentified network" / "Local only" (sometimes even as participating in the same unidentified network.)  "Local only" is correct, as I don't want to use them as default routes; and I certainly care that I can't name them, but I would like to figure out how to set things up so that I don't have to mark them as Home/Private networks every boot.
What makes a network "unidentified"?  Absence of a gateway? dhcpv6?  I tried adding a connection-specific DNS suffix to each :) 
What makes a network identifiable?
Thanks in advance for any information,
Arya
P.S. Here is what I assume is the relevant part of my ipconfig /all output:

Hi
Use this powershell script it makes necessary changes in registry i found it on the web looking for solution to the same problem under vmware network adapters and modified it to work with tap open vpn devices.
# see http://msdn2.microsoft.com/en-us/library/bb201634.aspx
# *NdisDeviceType
# The type of the device. The default value is zero, which indicates a standard
# networking device that connects to a network.
# Set *NdisDeviceType to NDIS_DEVICE_TYPE_ENDPOINT (1) if this device is an
# endpoint device and is not a true network interface that connects to a network.
# For example, you must specify NDIS_DEVICE_TYPE_ENDPOINT for devices such as
# smart phones that use a networking infrastructure to communicate to the local
# computer system but do not provide connectivity to an external network.
# Usage: run in an elevated shell (vista/longhorn) or as adminstrator (xp/2003).
