Security and Privacy
Like all browsers, Internet Explorer keeps a record of every website you visit in your browsing history. You may want to remove some or all of your browsing history for the sake of privacy.
Internet Explorer makes it easy to delete some or all of your history. For example, sometimes you might want to remove only your history from the past hour instead of removing your entire history. You might also want to remove all of your saved pages and cookies but keep your saved passwords.
For added privacy, Internet Explorer also offers private browsing, which allows you to browse online without recording your history or storing cookies. This is a great way to keep your browsing history secret when planning a party or buying a gift for someone who shares your computer.
Private browsing does not make Internet Explorer more secure—it only stops Internet Explorer from saving history and cookies for that session. Don't use a private window to view any websites you wouldn't feel safe viewing in a regular Internet Explorer window.
