This is being done via their new user interface which includes a new browser, integration with Microsoft's digital personal assistant Cortana.
Bing is point blank useless and the easiest way to disable the originally Windows 10 settings is to go to defaults and priortise Google Chrome and Google search as the services you want to use when browsing and searching online.
While the Start menu return is a welcome addition the system's heavy reliance on Bing search is a real pain in the backside.
Bing is the default search engine not only in Edge, but also in Cortana, which appears on the Windows 10 desktop in the form of a search box in the task bar. Some people who prefer to use Google or other search engines have gone to forums in the tens of thousands to express their annoyance that they are constantly being pushed to use Bing.
Changing the default search engine in Edge is fairly straight forward. All you need to do is go to the search engine's home page in Edge, click the menu button (three dots in the top right corner), select "Settings" and then "View advanced settings".
You then need to scroll down until you see the "search in the address bar with" box and select "add new". You can then select the search engine you want to use and click "add as default".
Changing Cortana's default search engine is less straight forward. Cortana is built to draw answers from Bing, and Microsoft really wants it to stay that way. However, less than 48 hours after the launch of Windows 10, developers have already come up with a workaround - and it's incredibly simple.
The first thing you need to do is download Google Chrome and set it as your default browser. Then you need to install an extension for Chrome, like Bing2Google or Chrometana that redirects your Bing searches to Google instead.
Once installed, this extension will redirect any Bing search in your browser to a Google search for those same search terms. So even if you go to Bing.com and type in a search, it will give you the answer in Google.
Once you've done that, you're ready to go. Type a query into the Cortana search box on the desktop and watch your answer from Google pop up in Chrome.
