I think it's probably a good idea to check the registry keys (`HKLM\SOFTWARE\GitForWindows`, etc.) and `where git`. The Git for Windows installer has an option to keep user's PATH unmodified, but the default one is to add the git.exe directory to PATH. It's also possible that users install other Git clients or use portable Git binary, which do not set the `GitForWindows` registry keys. By checking both the registry and `where git`, we can cover as many different user's configurations as possible.
