If you listen to us you have to understand that these questions don't just come out of nowhere. This one came about because Doug and I were sitting in a room trying to get some work done and we couldn't figure out how to remove the settings for existing network connection.
We knew we have done this in Windows 7 and Windows 8.0 but we just couldn't find it in Windows 8.1. And the reason we couldn't find it is because it's gone. There is no user interface to remove an existing wireless Internet connections in Windows 8.1.
You can do it. You have to go to the command line and type some arcane command using the net command and no one knows how to do it offhand, But we do have a tip on the website which will lead it will link that shows how to remove an Internet connection setting with Windows 8.1. Give it a look if that's something you need to do.
