Hi Gene. I'm Greg, an installation specialist and 9 year Windows MVP here to help you.
It should not be normally. Check if it's been added to any of the Startup program locations by following Step 4 in this checklist: http://answers.microsoft.com/en-us/windows/wiki...
If not I will walk you through the fixes for Edge to try progressively until it's fixed:
Back up your Favorites first in Edge Settings > Import from another Browser > Export to a File. If it won't open you can reach Favorites to back them up to an HTML file using the tiny app Manage Edge Favorites here: http://www.emmet-gray.com/Articles/EdgeManage.html
You can reset Edge in Settings>Apps>Apps and Feature, scroll down to Microsoft Edge, highlight it, choose Advanced Options, then Repair, or if that fails, Reset.
If that doesn't help then try re-registering the app following Option Two here: http://www.tenforums.com/tutorials/3175-apps-re...
If necessary you can reinstall it from this link: http://www.intowindows.com/how-to-reinstall-mic...
I would have several other browsers available to choose from on the Task Bar since Edge is a work in progress and unreliable. I use Firefox, Edge and Chrome in that order of preference. You can import Favorites from each other easily in Settings.
If nothing else helps then run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This will also bring it up to the latest version which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m...
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
