Auto updating the prompt isn't possible in CMD unfortunately. I do believe it's possible in powershell, but that's not my cup of tea. I do have a batch script that gets the branch and re-sets my prompt. You could create a git.bat that calls such a script on every git command, or like me, create `vf.bat` that I use to cd and update the prompt at once.

posh-git is a great powershell module that shows your current branch, has customizable colors, and adds tab completion to git commands. I think that stuff should stay as add-ons rather than be built into the console host.
