    # "To prevent the window button from being placed on the taskbar, create
    # the unowned window with the WS_EX_TOOLWINDOW extended style. As an
    # alternative, you can create a hidden window and make this hidden window
    # the owner of your visible window. The Shell will remove a window's button
    # from the taskbar only if the window's style supports visible taskbar
    # buttons. If you want to dynamically change a window's style to one that
    # doesn't support visible taskbar buttons, you must hide the window first
    # (by calling ShowWindow with SW_HIDE), change the window style, and then
    # show the window."
