I delete C:\Windows\SystemApps\Microsoft.MicrosoftEdge_8wekyb3d8bbwe but it remain on the all apps list. It didn't work but I want to remove it too.
This has an easy solution. Unpin Edge from your taskbar and ignore it. Use another browser like Firefox or Incredimail, or somebody else. Pin the new browser to your taskbar. Don't be like me and waste a week trying to find a work-around.
