主要是使用KernelIOControl这个函数
CString GetSerialNumberFromKernelIoControl()
{
          DWORD dwOutBytes;
          const int nBuffSize = 4096;
          byte arrOutBuff[nBuffSize];

          BOOL bRes = ::KernelIoControl(IOCTL_HAL_GET_DEVICEID,
                                       0, 0, arrOutBuff, nBuffSize, &dwOutBytes);

          if (bRes)
          {
                  CString strDeviceInfo;
                  for (unsigned int i = 0; i<dwOutBytes; i++)
                  {
                          CString strNextChar;
                          strNextChar.Format(TEXT("%02X"), arrOutBuff);
                          strDeviceInfo += strNextChar;
                  }
                  CString strDeviceId =
                          strDeviceInfo.Mid(40,2) +
                          strDeviceInfo.Mid(45,9) +
                          strDeviceInfo.Mid(70,6);

                  return strDeviceId;
          }
          else
          {
                  return _T("");
          }
}
