Put your script in Ruby's bindir. This command:
    ruby -r rbconfig -e "puts Config::CONFIG['bindir']"
will print it, on Windows something like "C:\ruby\bin".

The OneClick Installer usually sets up the file extension
association *.rb => Ruby interpreter, thus you should be
able to run your script by typing its name with the .rb extension, 
like:
    arf_cmp.rb

And if that doesn't work, try:
    ruby -S arf_cmp.rb

How does it work:
When you install Ruby with the OneClick Installer, it permanently
adds Ruby's bindir to the Path environment variable with the help
of the registry. Whenever you start a program (not only a ruby
script) from the console, the console will look for the program
file in the directories listed in the Path environment variable
and start the first it can find.
