Is there a way to move the taskbar to another monitor?

Simple Way

1. If you have the Taskbar locked you’ll need to right-click on it and uncheck the option that says Lock the Taskbar.
2. Now here’s the big one…drag the Taskbar onto the other monitor! You can put it wherever you would like.

Using Software

Smart Taskbar can add a taskbar to each monitor

Using Keyboard

1. press either the Windows key or Ctrl-Esc to pop the Start Menu up
2. press Esc to close it. The taskbar now has the focus
3. press Alt-Spacebar to pop the context menu for the taskbar
4. press M to trigger the 'move' function
5. use the arrow keys to move the cursor to another edge of the monitor(s) or press one of the arrow keys and then move the mouse. The Taskbar is now 'attached' to the end of the cursor, so moving the cursor near one of the monitor edges will snap the Taskbar there

You can also select 'Size' (S) instead of 'Move' to easily resize the Taskbar.

It's probably best to simply change which monitor you're using as your main display. per:

• Right click the windows background
• Screen Resolution
• Click the thumbnail of the monitor you'd like the task bar on
• Notice the little "make this my main display" checkbox that appears
• check it.

Typically, choosing your default monitor will move the task bar, but not always. This can happen if you have previously moved the start menu/task bar, or if you use software that manages your multi-display setup, like DisplayFusion. If you select a default monitor and your task bar doesn't move to the new default display, you can move it using the method described by joe.
