In what ways is he trying to get into your system and how do you know
this?  Do you have any "services" running on your machine?  If nothing
is listening on any ports, then there is no way to get in.  (or if
something is blocking all ports at the TCP/UDP or IP level)

Get a Linux or *BSD system to act as a firewall.  Then the only stuff
that can get to your windows machine is responses to requests that
originated from the windows machine.

Most likely because he can.  Some people are un-nice like that.



For society, it's probably a good thing that engineers value function
over appearance.  For example, you wouldn't want engineers to build
nuclear power plants that only _look_ like they would keep all the
radiation inside.
