How do I turn off the shuffle feature of my playlist?

Find the menu for your program. That is usually in the upper right corner of the screen, but sometimes at the bottom. Click each option and read the menus you get to see what you can do and where the button is. Music and video players usually have something at the bottom of the screen, usually a button with a curved arrow on it, to control play once , replay once, replay all, scramble, options.

You should also do this with the "Start" button in the lower left, and with every program you ever use. Then you can claim to know how to operate a computer, beginner level.
