I’ll forever struggle to remember how to configure Internet Explorer 11/10/9/etc to use Google and not Bing when searching from the address bar. Sure you can add providers from the Manage Add-ons menu but it never seems to work for me as the list of search providers that appears on the IE Gallery site—when clicking through from IE itself—doesn’t seem to include Google.
Instead I follow this URL in IE, click the button and tick all the boxes on the popup:
