There are two free editor's that I recommend for Windows: JEDIT and Notepad++. I am currently using JEDIT because of the ease of directory access to files. You will find that RAILS uses the directory structure for it's MVC model and JEDIT is ideal for this. JEDIT also saves automatically previous file versions - so if you modify and save the file, JEDIT will first copy and rename the file and then write over the working file once saved. This feature can really save you by restoring in case you make a mistake..

The links for the two free editors will be located at the LINK panel....
