Yeah.  It seems to be a bit on the ugly side...

 From reading other posts, i seems there are a lot of GUIDs and that 
most of them aren't "real" in the sense that they aren't associated with 
any hardware.

If I have 10 network interfaces on a Windows box, are they all named 
something like "Local something-or-other"?

Other posts seem to indicate that you can rename your connections.
