I have been very happy with Homebrew some far. What are some good windows alternative? Making the move from OSX to Windows in a week.

Windows 10 now has support for the Ubuntu subsystem. You have to flip some settings to enable it and install it, but it's very easy to setup and it creates a complete Linux shell within Windows, including full support for apt-get.

I found the default terminal pretty lacking, but you can now use mintty as the terminal: https://github.com/mintty/wsltty

With this, it's possibly a better Unix experience than macOS. I haven't used it enough to confidently make such a big statement, but it's worked very well so far in my trials.
