windows 7 - What's the point of the UsersDefault profile?

I'm a linux user and don't really know all that much about Windows stuff. I'm changing the default \Users directory and I see that there's a Default user profile at \User\Default that's a hidden link or something. What's the point of this?

Answer

Creating new users copies that data into the users' profiles, therefore it's the "default" settings etc. Here and here are articles about these defaults.
