Question

Q2 what does Lock the taskbar option helps
to do?​

Answer 1

Answer:

This feature doesn't allow the taskbar to move along the sides. You can keep the taskbar in one place by locking it, which can prevent accidental moving or resizing. If you unlock it, you can drag the taskbar to resize or move it to the bottom, left or right side, or top of your display(s).

Hope this helps!!
