Use WIN32OLE_EVENT.
Try following script.
-----
objWMIService = WIN32OLE.connect("winmgmts:\\\\.\\root\\CIMV2")
SQL = "SELECT * FROM __InstanceCreationEvent WITHIN 1 WHERE TargetInstance ISA 'Win32_Process'"
mySink = WIN32OLE.new('WbemScripting.SWbemSink')
ev = WIN32OLE_EVENT.new(mySink)
ev.on_event("OnObjectReady"){|objObject, objAsyncContext| 
  puts "Creation of " + objObject.TargetInstance.Name
}
objWMIService.ExecNotificationQueryAsync mySink, SQL 
while 1
  WIN32OLE_EVENT.message_loop
end
