Here's how one bridges 2 internet connections in Windows 7
A network bridge is software or hardware that connects two or more networks so that they can communicate. You can create only one network bridge on a computer, but one bridge can handle any number of network connections.
Open Network Connections by clicking the Start button Picture of the Start button, and then clicking Control Panel. In the search box, type adapter, and then, under Network and Sharing Center, click View Network Connections.
Hold down the Ctrl key and select each internet network connection that you want to add to the bridge.
Hold down ALT to reveal Advanced Menu and click Bridge Connections. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
You should now have a new network type named "Network Bridge" created.
Now Bridge the internet connection from your android phone with your alternate connection you usually use as described above.
Leave this internet bridge on your system.
Assuming one would use USB tether internet where home connection is unavailable, when you now connect your phone, instead of showing it as a NEW CONNECTION EACH TIME, Windows will directly recognize it from the internet bridge. This will stay so even after you restart your system and you are saved from registry tweaks.
