Take a look at this

http://ruby.railstutorial.org/

but, I recommend you to use ubuntu. Sometimes you may find some troubles in windows

If you need to stay on windows, you can use the rails installer from
http://railsinstaller.com. It makes setting up a development environment on
windows simple.
You may have issues with some gems in the future, but this will get you
started. Also take a look at http://railstutorial.org, it's an excellent
resource to get you started.
