I want to delete the unique session

Hello,
When I start my PC, I click on my session so that, i can load my settings and I finally arrive on the desktop.
(There was only my session).
I want to delete this unique session to arrive directly on the Windows desktop.
I read that I had to create another session "Admin" in order to remove my session, but the problem remains the same as I would always click on the new session before arriving at the desktop.
Thank you very much.
