Git for Windows
There may be instances where you'll need the command line interface for Git to set a various range of settings for Visual Studio, as Visual Studio may be unable to perform the setting or operation itself.
To install, download the appropriate version of Git for Windows from Git - Downloading Package (git-scm.com), it is recommended that the 64-bit Git for Windows Setup is used.
Administrator level access is not required as Git for Windows can be installed using a basic user account.
The defaults during setup process screen are fine to use.
Set Proxy Authentication
When Git for Windows is installed, you can edit and run the following command in command prompt to set the proxy authentication for your particular work environment:
git config --global http.proxy http://proxyUsername:proxyPassword@proxyServer:proxyPort
