Command-line Git on Windows

I had the same issue and resolved it by adding the /bin directory location to the PATH Environment Variable.

1. Search for the file location where Git was installed, mine is C:\Users\(My UserName)\AppData\Local\GitHub. It may also be C:\Program Files (x86)\Git

2. Once you have the location of Git you should see a /bin sub-folder. It may be in a PortableGit folder (mine is
   PortableGit_015aa71ef18c047ce8509ffb2f9e4bb0e3e73f13). Copy this path.

3. Go to Control Panel > System > System Protection > Advanced > Environment Variables

4. Choose PATH, click edit and paste the bin path there. If there are already any values in your PATH paste your Git path at the end separated with a semi-colon.

Now you can access Git command from CMD.
