Start screen
The Start screen appears to hide all tiles on boot, until you start interacting with them.

Start button
It is possible to hide the Start button in this build (this is also possible in builds as far back as 7927). To do this, you need to open up Registry Editor, navigate to HKCU/Software/Microsoft/Windows/CurrentVersion/Explorer, make a new DWORD called "YouBettaHideYoPearl" and set its value to 1. To apply changes, log off and log back in. Although the Start button will now no longer appear, File Explorer may not work properly at first. The only way to fix File Explorer is to restart its process.
