Subject: *.rb not running on Windows any more

At work, I installed 1.8.2 from the one-click.
I wrote a handy utility named "findfile.rb", and put it in my
windows\system32 directory.
I was happy, because I could open any cmd window and type "findfile
..." and my ruby script would kick the crap out of Windows' built-in
search features.

But then I installed 1.8.4 from the one-click.
Now, when I type "findfile ..." in a command window, Windows rudely
informs me:
"'findfile' is not recognized as an internal or external command,
operable program or batch file."

The findfile.rb file is still in the same spot.
Ruby was installed in the same spot.
I've tried associating *.rb with c:\ruby\bin\ruby.exe and
c:\ruby\bin\rubyw.exe, but to no avail.

Who can help me in my quest to continue to kick the crap out of
Windows' built-in search?

(For those interested, following is my hack script. It was originally
written to allow regexp filename searching, and was later expanded to
allow regexp content searching, too.)

require 'rubygems'
require_gem 'Usage'
usage = Usage.new "name_regexp [content_regexp]"

class Dir
  def self.crawl( path, max_depth=nil, depth=0, &block )
    return if max_depth && depth > max_depth
    begin
      if File.directory?( path )
        files = Dir.entries( path ).select{ |f| f[0,1]!='.' }
        unless files.empty?
          files.collect!{ |file_path|
            Dir.crawl( path+'/'+file_path, max_depth, depth+1, &block )
          }.flatten!
        end
        return files
      elsif File.file?( path )
        yield( path, depth )
      end
    rescue SystemCallError => the_error
      warn "ERROR: #{the_error}"
    end
  end

end

start_time = Time.new
name_match = Regexp.new( usage.name_regexp, true )
content_match = usage.content_regexp && Regexp.new(
".{0,10}#{usage.content_regexp}.+", true )

matching_count = 0
Dir.crawl( '.', usage.max_depth ){ |file_path, depth|
  if File.split( file_path )[ 1 ] =~ name_match
    if content_match
      if IO.read( file_path ) =~ content_match
        puts file_path,"  #{$~}"," "
        matching_count += 1
      end
    else
      puts file_path
      matching_count += 1
    end
  end
}
end_time = Time.new
puts "(Found #{matching_count} files in #{end_time-start_time} seconds)"
