It is the backup privilige. I add the following code before open the key.
   static HANDLE           hToken;
   static TOKEN_PRIVILEGES tp;
   static LUID             luid;

   // Enable backup privilege.

   if (OpenProcessToken( GetCurrentProcess(),
      TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken )== 0)
   {
         dwError = GetLastError();

        GetErrorMsg(dwError);
    }
   if (LookupPrivilegeValue( NULL, "SeBackupPrivilege", &luid ) == 0)

   //if (LookupPrivilegeValue( NULL, SE_BACKUP_NAME , &luid ) == 0)
   {
         dwError = GetLastError();

        GetErrorMsg(dwError);
    }
   tp.PrivilegeCount           = 1;
   tp.Privileges[0].Luid       = luid;
   tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
   if (AdjustTokenPrivileges( hToken, FALSE, &tp,
      sizeof(TOKEN_PRIVILEGES), NULL, NULL ) == 0)
   {         dwError = GetLastError();

        GetErrorMsg(dwError);
    }

It works. I tried  adding this code before. But I was adding this after openkey. In order to get this work, the privilege has to be granted before open the key.

Thanks a lot for the help. I also thought RegOpenKeyEx and RegSaveKey fill in GetLastError.
