Edge tries to be helpful by compiling interesting articles based on what it determines as the user's preference. These articles are handpicked from MSN.

If you are annoyed by the News feed and wish to turn it off, open the Menu via the top right corner. Go to 'Settings->Open New Tabs With' and select 'Top Sites' or 'Blank Page', at which point the News feed is successfully disabled.
