// SelectQuery selectQuery = new SelectQuery(queryString);

// ManagementObjectSearcher searcher = new ManagementObjectSearcher(selectQuery);

// foreach (ManagementObject mo in searcher.Get())
//{

// object tempID = mo["HardwareID"];

// if (tempID != null && tempID.ToString().ToUpper() == HardwareID.Trim().ToUpper())
