make itunes default media player, windows 10

I want itunes to be the default media player for all files it supports, I tried some of the suggestions posted but they don't work inn W10, Microsoft isn't going to make it easy for anyone to chose apps other than theirs but I mostly hate the windows apps and all of my media is either itunes or Amazon so itunes. itunes isn't an available option in ay of the drop down menus when selecting default apps by file type, which makes it nearly impossible to choose it as default. 'warn me when itunes is not my default" has always been checked but I've never seen a warning.
