Mine is sitting there also and will continue to sit there until I hear 100 people say they had no issues downloading and installing it. Or Microsoft downloads it and Installs it. It says "When you are ready to click to download and install. Well not going to happen by my stroke of the keyboard any time soon.
I used to let the New Upgrades for Internet Explorer sit. I had the box checked to notify me but don't download and install, let me choose. I would let it sit for over a year before I would Upgrade Internet Explorer. I have Internet Explorer 11 now, but don't use it. For the past 2 years I have not used Edge, except to get my mail. I used Chrome, because Edge would not load half the stuff I needed. Just recently I got the New Edge, and YES it works great. So I do have to say Thank You Microsoft for that.
