If it’s on auto-hide and on the left or right of the screen, you simply might not have noticed it. Just in case, you should also check to make sure the taskbar is located at the bottom of the screen.
That will open up the taskbar properties dialog box where you will want to go ahead and uncheck the Auto-hide the taskbar box. To do this, you would normally have to right-click on your taskbar, but since that is missing, we have to go through the Control Panel and click on Taskbar and Navigation.
