uninstalling edge can cause you to loose all network connectivity. I made the same mistake sometime ago and the advice given to uninstall just crashed my system. after rebooting the old edge was restored but all network connectivity was gone. The system was not able to connect to the internet or any network - there just wasn't any network options. The only way to fix the problem was to Ghost my system back. After restarting, i still get the option to update edge, but I will never click on it again. Microsoft should not impost drastic changes to software and should make any new features/changes available under the options settings, that way if you don't like something (which most people don't) you can just uncheck the option.. MS didn't do this with the latest update to edge and created a nightmare for many users. The advice given here is pretty much next to useless.
My suggestion to everyone is to maintain a compete image backup so that when these situations occur (which they will with Microsoft) you can easily just restore the image. The checkpoint/restore feature of windows is practically useless in situations like this and you need a real backup method. Ultrabac is one such reliable backup/restore mythology.
