 Dir.chdir "#{windir}\\Microsoft.NET\\Framework\\v4.0.30319\\"
 require 'System.Management'
        
 options = System::Management::ConnectionOptions.new()
 options.Username = username

 path = System::Management::ManagementPath.new("\\\\#{machine_name}\\root\\cimv2:Win32_Process")
 scope = System::Management::ManagementScope.new(path, options)


 scope.Connect()


 opt = System::Management::ObjectGetOptions.new()
 class_instance = System::Management::ManagementClass.new(scope, path, opt)


 in_params = class_instance.GetMethodParameters("Create")
 in_params["CommandLine"] = command


 # Execute the method and obtain the return values.
 out_params = class_instance.InvokeMethod("Create", in_params, nil)
