I recently used this to capture stdout and stderr after running
Schtasks.exe on many windows servers SOX audit of scheduled jobs.

I then called it like this
@taskScheduler =,@commandArgs)

P @taskScheduler._stdout

# This class executes a Microsoft Windows DOS command
# and holds the results of stdin and stdout in
# object attributes.
require "win32/open3"

class Win32Command
  attr_reader :_stdout, :_stderr
  def initialize(command, arguments)
    @@command = command
    @arguments = arguments
    @commandLine = @@command << " " << @arguments
    @_stdin, @_stdout, @_stderr = Open3.popen3(@commandLine)
    @_stderr.sync = true
