  4. Click Clear to confirm your choice.
  5. Click the Clear button under “Other Cortana Data and Personalized Speech, Inking and Typing.” This will clear the info saved from your calendar, contacts, location, and browsing history.

  7. Follow the other links on the page to clear or manage additional saved info, such as your saved places in Bing Maps, Bing search history, and saved info for Xbox, OneDrive, Outlook, and Microsoft Advertising.
