Thanks, this works for me:

require 'win32ole'

def create_environment_variable(var_name, value)
  wmi = WIN32OLE.connect("winmgmts:\\\\.\\root\\cimv2")
  env_var = wmi.Get('Win32_Environment').SpawnInstance_

  env_var.Name = var_name
  env_var.UserName = "<SYSTEM>"
  env_var.VariableValue = value
  env_var.Put_
end

var_name = 'ABC'
value = 'SOME_VALUE'

create_environment_variable(var_name, value)
