The default search engine in Microsoft Edge is Bing. Edge is Microsoft’s web browser, and Bing is Microsoft’s search service, so the two are closely integrated across Windows and Microsoft accounts.
Users can change Edge’s search engine in the browser’s privacy and address-bar settings. That means Google, Yahoo, or DuckDuckGo may be a user’s personal choice, but they are not the browser’s standard default installation choice.
Bing began as Microsoft’s successor to earlier services such as MSN Search and Windows Live Search. Edge replaced Internet Explorer as Microsoft’s main browser, while Bing remained the company’s built-in search option. A common mix-up is confusing the browser’s default with the search engine a particular computer, organization, or user has configured.
