How to Return to Traditional Desktop

I went through all the settings last night, making changes as desired, and somehow managed to screw up my desktop. Instead of seeing my icons on the background and in the taskbar, I have a bunch of start menu tiles covering the screen. I know it's probably a simple matter to return to my old desktop, but I can't seem to find the correct setting to change back. Can anyone help?

I believe you have turned on the full screen start menu, revert by going to settings/personalization/start then under the "Use Start full screen" turn it off.

I did what you said, but that didn't fix the problem. It's also annoying that I can't close a program the usual way. I have to click on the task view button and close it that way.

That did it. Thank you very much.
