Learning Scheme / SCIP

So I want to read SICP and learn functional programming. I decided to start with Scheme.
Which implementation should I use for starting to learn Scheme? It has to run on Windows but it doesn't need to be integratable in a IDE.

``Use MIT Scheme'' is an ancient African word meaning ``it's the only one I've used because it's in the apt repo.

UCB Scheme is the superior implementation.
