GUI Clients for Windows

There are several Graphical User Interfaces for git available under Windows, see for example this list. Note, you can use several tools on the same repository. Subjective recommendation to use the following two GUI tools:

1. SourceTree (free; no administrator rights needed for the installation; however SourceTree utilizes .NET and if the "right" .NET version is not present, it must be installed and this installation requires administrator rights).
   Recommended for beginners, since simple GUI and nice tutorials. It is reasonably simple to learn how to work with git. Also, the different versions of the code (at least: local copy + local repository + remote repository) are clearly shown and more advanced operations like branching are visually supported.
2. TortoiseGit (open source; requires administrator rights for the installation).
   Recommended for people working with TortoiseSVN previously. Furthermore, TortoiseGit is nicely integrated in the Windows Explorer browser and allows very quick basic operations (e.g. commit to local repository and push at once to remote repository). Since the file tree is visible with icon overlays in Windows Explorer, it is simple to manage repositories with many files.
