The example commands from the article are all available with the git distribution:
> cp -a
> find | xargs | rename
> grep | xargs | sed
You can do all that - plus ssh (with ssh-agent) from the DOS prompt (you don't need PS, PuTTY or git bash).
There's vim too that comes with syntax highlighting, for which there's solarized dark/light colour palettes for the DOS prompt [1], as well as decent enough consolas fonts that you can use.
You can do an `ls *.exe` in the C:\Program Files\Git\usr\bin directory to see the list of programs that are there.
Now that Windows 10 has done some 20 year late improvements to the underlying console window [2], you can properly resize the window and the text flows properly.
The only thing I miss are the `history` and `!` commands for which I wrote a hacky bat file implementation of [3].
Edit: Clink [4] appears to be a fully compatible GNU history (Readline) implementation.
Chocolatey is pretty awesome too.
