Not a fan of Microsoft Bing? That's ok, it's easy to change the default search engine to any site that supports the OpenSearch standard such as Google, Yahoo or even DuckDuckGo. This tweak will only change the search engine setting for Microsoft Edge. It is not currently possible to change the search engine used by Cortana as it is deeply integrated with Bing.
Let's get started by opening Edge and clicking on the three dots on the end of the menu bar to bring up the menu.
Then, select Settings.
On the Settings menu scroll down until you see the button for Advanced Settings and click it.
Next, on the Advanced Settings screen, scroll down until you see "Search in the address bar with" and select <Add new> in the drop down list.
Finally, you will see a list of OpenSearch compatible search engines that you have visited. Click the search engine you want to use, and then hit the Add as default button and you are all set.
