auto updates? possible? easy? how?

http://vbforums.com/showthread.php?t...ctory+problems
i was looking here and saw talk of auto updates, is this easy to set up. I would like it mostly for me and my development team, but it would be cool for the users of my game to have the updates as they are coded, and not have to redownload it. I am new to all this application dev stuff and have no idea about anything.

But I would like to learn about the auto update thingy
