In Windows 7 I can only have my taskbar on my main display. Can I extend the taskbar across multiple monitors in Windows 8?
Yes. Windows 8 allows taskbars to be shown on all displays. To do this:
- Right-click the taskbar and select Properties.
- Under Multiple displays, select Show taskbar on all displays.

Yes, just choose the "Extend these displays" option in the Screen resolution context menu (right click anywhere on desktop).
Windows 8 includes support for taskbars on multiple monitors.

Be aware that you can only pin to the main taskbar. See Is it possible to pin an application to the taskbar on a secondary display? for details.

The taskbar can span all display. Additionally, you can configure the taskbar menu to open on the monitor that has the active window, on all monitors, or on the main taskbar and the taskbar on the active window's monitor.
