Removing live tiles (?) Not sure what they're called from Desktop

I'm transitioning to a PC after using a Macbook Pro for many years. Tonight my desktop starting showing these live tiles (?), I'm not certain what they're called, on the left of my screen. I'd rather not see them and simply see my desktop. It seems like it's also making my desktop slightly dimmed. I tried to remove this set up by unpinning each tile, but it's still here. Help! Thanks in advance.

Turns out I was in Tablet mode!!
