Hi Charles. I'm Greg, an installation specialist, 10 years Windows MVP, and Volunteer Moderator here to help you until the problem is solved.
What toolbar? Are you perhaps referring to the Task Bar at the bottom of the page?
If so it has an option to auto-hide so it goes away until you move your mouse there. Go into Windows Settings > Personalization > Task Bar and choose Automatically Hide the TaskBar.
If that's not what you need, then please explain in more detail so I can help you better.
