The taskbar at the bottom of the screen is “unmovable” by default, but it is possible to customize the number of “Quick Launch” buttons or extend the width of the bar. To do this, right-click the bar and uncheck “Lock Task Bar.” Adjust the bar to your liking by clicking and dragging the dotted “borders” of different parts of the task bar. To lock it back in place, right-click the bar one last time, then check “Lock Task Bar.”
