Change the default search engine in Microsoft Edge
Microsoft suggest using Bing for an enhanced search experience in Microsoft Edge on Windows 10. Keeping Bing as your default search engine gives you:
Direct links to Windows 10 apps, taking you straight to your apps faster.
More relevant suggestions from Cortana, your personal digital assistant.
Instant help to help you get the most out of Microsoft Edge and Windows 10.
But Microsoft Edge uses OpenSearch technology, so you can change the default search engine.
In the Microsoft Edge browser, enter the search engine’s website (for example, www.contoso.com) and open that page.
Select More actions (…) > Settings , then scroll down to select View advanced settings. In the list under Search in the address bar with, select Change.
Select your search engine’s website, then select Set as default. If you don’t select the search engine, the Set as default button will be greyed out.
