Microsoft recently shared this,
"Protecting the Integrated Search Experience in Windows 10
Unfortunately, as Windows 10 has grown in adoption and usage, we have seen some software programs circumvent the design of Windows 10 and redirect you to search providers that were not designed to work with Cortana. The result is a compromised experience that is less reliable and predictable.
The continuity of these types of task completion scenarios is disrupted if Cortana can’t depend on Bing as the search provider and Microsoft Edge as the browser. The only way we can confidently deliver this personalized, end-to-end search experience is through the integration of Cortana, Microsoft Edge and Bing – all designed to do more for you.
Starting today, to ensure we can deliver the integrated search experience designed for Windows 10, Microsoft Edge will be the only browser that will launch when you search from the Cortana box."
To be clear, this only pertains to when users want to utilize Cortana to search, and has nothing to do with your search engine of choice when you are browsing.
It should probably come as no surprise that Microsoft would go this direction. After-all, Cortana and Edge are both Microsoft products that are part of Windows 10. Those who are fans of Google or Siri Search may be miffed by this, but it was probably inevitable at some point. In fact, both Google Now and Apple's Siri lock you into their search engines when using their voice search as well. What do you folks think?
