Poll: Label in the notification area

I do not understand something, or is it abnormal, when when I press the close button of an application, it does not close, but collapses into the notification area?

If the program I am developing involves minimizing to the notification area, I always do this only when the form is minimized, not when it is closed. If you think Close is the right button to minimize, please read the Windows UX Guidelines .

Here is an excerpt from this guide (page 792):

Minimizing programs to the notification area

Note: It is no longer recommended to use Windows 7. Minimize applications. Use regular taskbar buttons instead. Your program may support both mechanisms for backward compatibility.

If you need to:
- The program can have only a single instance.
- The program is a run for an extended period of time.
- The icon shows status.
- The icon can be a notification source.
- Doing so is optional.
• Use the Minimize button, not the Close button.

And the translation:

Minimize the program to the notification area

Note: minimizing the program window in the notification area is no longer recommended for Windows 7. Instead, use the usual taskbar buttons. Your program can support both mechanisms for backward compatibility.

• To combat clogging of the taskbar, it is necessary to consider the possibility of minimizing the program in the notification area only if the following conditions are met:
- The program can have only one copy.
- The program runs for a long period of time.
- The icon shows the status.
- The icon can be a source of notifications.
- This is a custom option.
• Use the Minimize button in the application title bar, not the Close button.

I was not guided by the recommendations of Microsoft in my opinion. And now I'm wondering: am I mistaken, or those users who are asking to do folding at closing?
