If I could, I'd like to suggest using Mercurial instead. It is vastly better supported on Windows, has a simpler workflow, and allows HTTP-based authentication--no SSH keys required. Plus, if you really need git-like flexibility--rebasing and whatnot--it's there in the form of Mercurial patch queues.
