By default, the thumbnail button is Visible. Windows 7 allows a maximum of seven buttons in the taskbar thumbnail. When the property is set to Hidden, the thumbnail button has no visible elements, but space is still reserved for it. When the thumbnail button is Collapsed, it does not have any visible elements and no space is reserved for it. In this case, additional thumbnail buttons in the ThumbButtonInfos collection are displayed.
