As Google does with its search engine, Microsoft maintains a history of all the searches you have performed from its search engine while logged into a Microsoft account, e.g., Hotmail, Outlook.com, etc. You can view the history of your searches conducted with the Bing search engine by clicking on Search History at the top of the Bing web page. If you click on that link, you will see links for "Recent searches" and for "Frequent searches".
