Start programming Lisp

Hello,
Some years ago, I did programs in Lisp at Artificial Intelligence class in the university and I became in love with the recursive approach to solve problems.
Today I would like to restart working with Lisp (without professional reasons) but I dont understand how to install a compiler in my PC (Windows platform).
It is enough I download a compiler and a runtime system? Where I introduce the code? Which is the most appropriate concerning my focus?
In the meanwhile, I starting refreshing my Lisp code knowledge dealing with a problem that interests me...
Anybody can help me?

I haven't worked with MS-Windows for a few years now, so I'm no big help here, but in the CLiki under Getting started there are some links to guides how to install and setup Common Lisp on MS-Windows and some other computer operating systems.

Download Lispwork Personal Edition from www.lispworks.com.

That will get you started big time.
