I’ve used Tortoise SVN for years and it makes things really easy for getting started with Subversion and integrating smoothly with Windows. However Git is a more confusing world. There’s two installations and neither one clearly refers to the other.
However it boils down to the following (you can accept all the defaults in the installation):
- Install Git for Windows (http://git-scm.com/download/win)
- Install Tortoise Git (https://code.google.com/p/tortoisegit/wiki/Download)
