  1. I think it’s not working anymore. Both Edge old and new appear in the Start menu, but when I’m opening the old edge, my laptop flicker for a second and nothing happens.

    The chromium edge is working flawlessly :-/

    1. As you can see in the screenshot in my post, both Edges work properly here.
      Also, why you have covered this tip on your web site if you find it non-working?

      1. Initially it was working, but now its not working and thats why made a comment here. Maybe im doing something wrong.

      1. Thank’s. That’s what I did but it never disappears completely. Very strange that Microsoft is still proposing it.

        1. They cannot kill it, some apps use Trident and there are many Enterprise websites that need IE, Java, Showave Flash and all that ancient junk.
          It may be useless for consumers, but essential for enterprise users.

  2. My Windows 10 updated two weeks or so ago, and replaced Edge with the newer version that no longer reads epub files. None of the Windows epub readers come close to simplicity and ease of use of Edge. Is there a way for me now, after the update, to run an epub-compatible Edge, and the newer version next to each other? Thanks!
