Many users set up multiple monitors on their computer that they can have room for more windows and panels on their screen. Using multiple monitors allows you to exercise greater control over how and where you navigate Windows. You can move just the task bar to another monitor; you can also move the entire desktop, including the task bar and icons, to a secondary display.
Move the Task Bar
Right-click on the task bar. Click to un-check the "Lock the Taskbar" menu item, if it has a check mark next to it.
