+   * Those compatibility mode options (95/98/ME) can only display and
+   * be selected for 32-bit application.
+   * If the compatibility mode is in effect, the GetVersionEx function will
+   * report the OS as it identifies itself, which may not be the OS that is
+   * installed.
+   * Note : 1) We only target for Win7 build number greater than 7600.
+   *        2) GetVersionEx may be altered or unavailable for release after
+   *           Win8.1. Set pragma to avoid build warning as error.
