Turn Off Windows Spam Suggestion Notifications
Click Notifications & actions.
Under Notifications, turn off the "Get tips, tricks, and suggestions as you use Windows."
Couple more things in there you might want to turn off as well, but leave on "sugest ways I can finish setting up my device to get most out of windows."
Sounds if you don't like them can be turned off as well, but you may miss an important notification.
NOTE: In 11 it's the same place just worded a bit different.
