On a new article at the official Windows Blog, the company said that the point of having Cortana in Windows 10 is learn about you and help you with personalized assistance. Cortana logics is powered by the Bing search engine, and in order for the company to provide an “end-to-end personal search experience”, this integration can’t be interrupted. The software giant also notes that there is a number of third-party utilities that alters the way Cortana is supposed to work by changing the default search engine to another provider (e.g., Google), and Microsoft Edge to a different browser (e.g., Chrome or Firefox). As a result, Microsoft is making changes to block any third-party tool or hack to change the default search engine and the web browser that Cortana uses to deliver a consistent experience. Although, Windows 10 never included a configuration option to change this behavior, tools such as the Chrometana extension for Chrome let users to trick Cortana into using Google as the default search engine and Chrome as its default web browser. While this might look like as a wrong move from Microsoft, it’s worth pointing out that Google Now on Android and Siri on Apple also have their default search settings locked down. Microsoft ensures that this change will only affect Cortana, and you can continue to use your search engine of choice on Microsoft Edge and on a different web browser.
