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 = Win32Command.new(@@win32Command,@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”  
$stdout.flush  
$stderr.flush

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  
@\_stdin.close  
end  
end
