Git, GitHub and Windows users
One of the difficulty of getting started with Git on windows is setting up ssh and a private/public key for authentication. With Git 1.7 however, you can use https for authentication and GitHub now support it:http://github.com/blog/642-smart-http-support
If all the that ssh stuff put you off Git in the past, you should try again.
Try Git Extensions to install Git:
(Git Extension only include Git 1.6.5)
