Unfortunately the ino command line toolkit is mac/linux only and command line arduino in windows is a lot of work.
Best install linux then. Windows never has had good support for the sort of customisation which you need and for commercial imperative reasons, it does tend to change whenever people get the hang of it.
Much of the linux environment including the font size is adjustable. High contrast high visibility desktop themes are widely available. Why would you want anything else?
