Go to the Control Panel and open up the Network and Sharing Center. You should see your new virtual adapter listed there (as shown in the screenshot above). Click the "Local Area Connection" link (or whatever shows up next to "Connections").
Click the Properties button in the window that appears.
Head to the Sharing tab and then check the "Allow other network users to connect through this computer's Internet connection" box.
Use the drop down menu to select the virtual network adaptor you've created.
Click OK followed by Close.
You should now be able to connect other devices to the network you created and enjoy a shared internet connection.
