Pik is a tool to switch between multiple versions of ruby on Windows.

Or to put it another way

 doskey rvm=pik $*  # (sort of)

You have to tell it where your different ruby versions live using 'pik
add'.  Then you can change to one by using 'pik switch'. You can also
get new versions with 'pik install'.

It also supports running commands/code with all versions configured.

 pik run  #  Runs commands on the command line
 pik ruby #  Runs using the ruby interpreter for each version
(ruby.exe, jruby.bat, ir.exe)
 pik gem  #  Runs using the gem command for each version  (gem.bat, igem.bat)

Requirements:

Windows, more than one version of Ruby (otherwise, what's the point?)
and Rubygems

Install:

1. If you've used a version previous to this one, you'll need to uninstall them.
  Don't worry, this will leave your pik config intact.

   pik run "gem uninstall pik"

2. Install the pik gem

   gem install pik

3. You need to install pik to a location that's in your path, but
someplace other than your ruby\bin dir

   >path
     PATH=C:\tools\;C:\ruby\186-p368-mingw32\bin;C:\WINDOWS\system32;C:\WINDOWS

   >pik_install C:\tools

4. Add all the versions of ruby that you want to use with pik
