In Microsoft Edge, perform a search in the address bar using the search engine you want to set as your default.
However, you can change the default search engine in Microsoft Edge to any site that uses OpenSearch technology. Keeping Bing as your default search engine provides an enhanced search experience in the new Microsoft Edge, including direct links to Windows 10 apps, relevant suggestions from your organization if you’re signed in with a work or school account, and instant answers to questions about Windows 10.
