Microsoft threw in the towel when it comes to win10's Edge browser, which they'd built from the ground up to challenge browsers from Google, Mozilla, & Apple. They've been working on a new version of Edge, this one using much the same core code as Google's Chrome browser, and while you can test it today, running alongside the old Edge, come next year, with rollout starting in January, it will automatically replace the original Edge that you've got installed now.
That would be less of a big deal if the new Chrome-based Edge was complete -- it isn't, nor is it going to be come February 2020. Internet Explorer was carried over into win10 because there are some things it can do that nothing else can. To a slighter degree the same thing also applies to the original Edge, though Microsoft has said it is trying to include most of the original functionality in the new version.
If you want or need to stop the automatic migration to the new Edge, the article has a link to a Blocker Toolkit from Microsoft that will prevent it from happening automatically. If you want to get an idea of what the new Edge can & cannot do, at least yet, head over to microsoftedgeinsider[.]com/en-us/ . It wouldn't be a terrible idea to install it either so you can give it a hands-on try, while it will still let you use the original. If you're running win10, next year, unless you install that blocker, you won't have a choice.
