Change My IP Address in Windows Vista

Hello Folks,

Usually I don't use Windows Vista, my laptop runs Ubuntu.

But today I helped remotely (by phone) my brother with a network problem he had, and the solution was "Change his IP Address in Windows Vista".

So I found a good tutorial about it:

This tutorial is good to send to people how doesn't know a lot of computers.
