Brushes

I'm not sure if this is allowed, so if it is- delete it.

I just recently made a new user name on my Windows XP because the other one was too slow. So, I have all my files on except for one thing- my brush files. I would like to know how I can get all my icon brushes from my old user name onto my new one.

P.S. I didn't save the files. v_^ And, this is really off-topic, but you can think of it as a bonus hehe: my computer's movement (scrollbar, opening programs) is really delayed, how do I fix it?
Thanks in advanced.
