 // Selection of the implementation works as follows:
 //   - Android always uses the NativeNotificationDisplayService.
 //   - Mac uses the NativeNotificationDisplayService by default but
 //     can revert to MessageCenterDisplayService via
 //     chrome://flags#enable-native-notifications or Finch
 //   - Linux uses MessageCenterDisplayService by default but can switch
 //     to NativeNotificationDisplayService via
 //     chrome://flags#enable-native-notifications
+//   - Windows 10 update 2016/07 and above use MessageCenterDisplayService by
+//     default but can switch to NativeNotificationDisplayService via
+//     chrome://flags#enable-native-notifications
 //   - All other platforms always use the MessageCenterDisplayService.
