Get rid of right half of start menu

Click the start menu button. The left half is the traditional side- the right half is the side with all those live tiles and windows 8.1/windows 10 style touch apps. How do I get rid of that right part?

Problem in my googling is that I don't know what it's called. Closest thing I've found is unpinning individual windows- that's not what I want. I just want to get rid of that whole right part.

Right click on and unpin all the tiles.
The Menu will collapse itself after it closes.

And why do you want to get rid of it ??
