Remarks
The DestroyWindow function sends the WM_NCDESTROY message to the window following the WM_DESTROY message. WM_NCDESTROY is used to free the allocated memory object associated with the window.
The WM_NCDESTROY message is sent after the child windows have been destroyed. In contrast, WM_DESTROY is sent before the child windows are destroyed.
A window receives this message through its WindowProc function.
This message frees any memory internally allocated for the window.
