"You should use the thumbnail toolbars in the new development instead of desktop ranges that are not supported on Windows 7." - MSDN
Unfortunately, it seems like Microsoft is discouraged by the creation of graphical interfaces in the taskbar, like what you are talking about. An alternative is to use taskbar extensions, as discussed here . MSDN seems to give some conflicting information on the taskbar extension page, directing developers to the IDeskBand2 page (where the quote is above). For future compatibility, I would recommend this.
