ขอคำแนะนำเรื่องการ register program พอมีวิธีฝังตัวเลขลงใน HardWare บ้างมั้ยครับ

 string drive = "C";
            ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"" + drive + ":\"");
            if (disk ["VolumeSerialNumber"] != null)
            {
                txtCode3.Text = disk["VolumeSerialNumber"].ToString();
            }
            else if ( disk ["VolumeSerialNumber"] == null || disk ["VolumeSerialNumber"] == "" )
            {
                ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
                foreach (ManagementObject wmi_HD in searcher.Get())
                {
                    if (wmi_HD["SerialNumber"] != null)
                    txtCode2.Text = wmi_HD.ToString();
                }
            }
