Among Microsoft Windows 7's features, a taskbar overhaul is arguably the feature in Microsoft's upcoming OS that has aroused the most interest. But it's also the most cloaked in mystery, as it was not part of the pre-beta Windows 7 software handed out to attendees at Microsoft's PDC (Professional Developers Conference) last month. More taskbar details emerged late last week on Microsoft's Engineering Windows 7 blog. Despite some criticism that the Windows 7 taskbar looks too visually similar to the Mac OS X dock, Microsoft does seem to be trying to break new ground with the look, feel, and functionality of the Windows 7 taskbar.
