lisp for windows

mainstream compiler/interpreter for lisp(windows vista)?

My idea is to present an image to children that it is good to be intellectual, and not to care about the peer pressures to be anti-intellectual. I want every child to turn into a nerd - where that means someone who prefers studying and learning to competing for social dominance, which can unfortunately cause the downward spiral into social rejection.
