Windows 10 brings a ton of sweet new features. Among them, you can now search the web directly from the Start menu. However, it will always use Bing. The Bing2Google extension for Chrome will redirect your searches to Google instead.
Once installed, this extension will redirect any Bing search in your browser to a Google search for those same terms instead. It will only work if Chrome is set as your default browser, and it won't actually affect any results you get within the Start menu itself (like "what's the weather like?").
It's worth pointing out that this extension will always redirect Bing to Google, even if you manually pull up Bing.com in your browser. While that may be all well and good for most people, Bing can occasionally do some things well, but you'll have to temporarily disable this extension to use it.
