Having just installed windows 10: disabling the browser change is well hidden. There's no customize "button" or link, there's a bit of text with no decoration or underline that's lighter and appears greyed out that says "customize" on a screen filled with text. The chances of a user discovering this unless they're actively hunting for this (like I was) are close to zero.
