The easiest solution is to install TortoiseGit. With this installed, you can right click the repository folder in Windows Explorer, select Git Sync from the context menu, click Pull in the dialog that pops up, and then close the dialog. Sending a pull request is just as easy with TortoiseGit, but you need to commit your changes to the local repository (right click on the folder and click Commit) before sending the pull request. The one caveat is the TortoiseGit needs MSysGit installed.
