The real multi-monitor support in Windows has task-bar only in the primary monitor that shows applications from all monitors. The extended monitors are plain without any taskbar. There is no other way to add another taskbar to the extended monitor.

Normal Windows extended to multiple monitors:

With Multimon Taskbar

We created MultiMon taskbar to solve this issue in our office. It creates a second (and third) taskbar which will be put on extended monitors. Each taskbar display items from that monitor only. The PRO version has additional features such as resizing windows to multiple monitors, moving to monitors, suspending the extended taskbars when the computer is connected via Remote Desktop and themed captions.

TaskBar PRO 3.5 Additionally to the free version Version 3.5 doesn't use any API hooking, it is super lightweight and doesn't affect or hook into windows or the applications. The Caption buttons (arrows) now work in all OS, including Windows 7 Works on both 32 and 64 bit OS Support for Windows XP, Media Center (Royale on XP), Vista (Royale Noir) and Windows 7 themes Add buttons to resize window across two or three monitors (good for spreadsheets etc..) Move To Monitor buttons on the extended taskbar can move even special windows like Remote Desktop Client Better handling moving windows across screens with different resolutions Monitors Remote Desktop and can Suspend itself when you are in RD session, then restore itself after RD session is finished Support for dual monitors if the primary monitor is on right Caption (arrow) buttons to quickly move window to monitor More consistent behavior of taskbar - cliciking on selected item will now minimize its window, like with original windows taskbar Tip: To change theme of your Multimon PRO taskbar click the Properties Button (or right click on empty space of the Multimon taskbar), click on Properties item in menu and change the Appearance. The theme of the MultiMon is independent from the Windows theme, so you can run Classic theme on your main XP taskbar and Vista theme on your extended Multimon taskbars. XP Royale theme: Royale theme is a special XP theme from Microsoft that was later used on XP Media Center Edition (blue version) and it become also blueprint for Vista theme (noir version). So if you use blue Royale theme on your XP, select Windows Media Center theme in MultiMon to match the taskbars. If you use Royale Noir, select Vista theme to match the taskbars. Vista Tip: Vista use hardware acceleration for its aero theme with direct writing to the display buffer. It would be therefore risky to add arrow buttons to the aero application bar. However the "secret" hotspots for the arrow buttons (visible on the XP and Vista classic) are still there and fully functional. Clipboard Extender A simple but cool Text clipboard extender can be added to the toolbar. It can be also rolled in or totally disabled. This little box will capture all text Copy to clipboard operation and store. Other hidden functionality of Clipboard extender: F3 - Search. Type any text and press F3, it will quickly search for the presence of this text in all stored copy operations and select matches. F5 - type any text and it will try to execute it. Type for example calc and press F5 Return - type any text and press return, it will be added to the clipboard list (and also copied to clipboard) DEL - unroll the combo box so you see multiple items, Move cursor over item so it is selected (but don't click) and press DEL to remove it from list. Resize across monitors (PRO version) Many programs, like spreadsheets, text editors, graphic programs have a MDI interface which means all client windows can be positioned only within the main program window. You can't display documents in single application side by side on different monitors because you are still limited within the main application window: Taskbar PRO has simple buttons to resize the main window across two or even three monitors and you can then simply move the documents around side by side.
