Guard Your Browser History

Edge sends your Internet browsing history to Microsoft in order to 'help Cortana personalize your experience'. You can turn this off by clicking on the ellipsis button in the top right corner of Edge, then go to 'Settings->Advanced Settings->-View Advanced Settings', and under Privacy and Services turn off 'Have Cortana Assist Me in Microsoft Edge'. And while you're in the Privacy and Services menu, make sure you turn off 'Use page prediction to speed up browsing, improve reading, and make my overall experience better'.
