c++ - Dynamic taskbar icon depends on configuration of taskbar? -

I have implemented the possibility of loading custom taskbar icons during the runtime (according to).

I now saw a strange behavior: the new taskbar icon is set correctly, but Windows 7 still shows the old (original) mark when "Taskbar Button" is always in the properties of "taskbar buttons" , Hide label "is configured for. On choosing one of the other options to display a custom icon.

So: What is the idea of ​​this or how does the problem of THS overcome? I want to show the custom icon in all configurations of the taskbar.

Thank you!
