Netflix is a television and movie streaming service that allows you to watch media directly and instantly through your computer. One of its features includes a "Recently Watched" list that displays your history of viewed movies. If there is a movie you have watched that you do not want others to see, you can remove it by clearing out your entire Recently Watched history. The only way to do this is to start a new account.
Log in to your Netflix account on its web site.
Click "Your Account & Help."
Click "Cancel Membership."
Return to the main Netflix page and recreate your account the same way as when you first created it. This will give you a clean Recently Watched history.
