As of the latest preview build of Windows 10 they’re splitting amicably.
An anonymous reader quotes a report from VentureBeat: Microsoft has announced a big change for how the Cortana search box in Windows 10 will work going forward: all searches will be powered by Bing and all links will open with the Edge browser. This is a server-side change going into effect today. Once it takes effect on your Windows 10 computer, Cortana will no longer be able to serve up results from third-party search providers, like Google or Yahoo, nor take you to a third-party browser, such as Google Chrome or Mozilla Firefox. Ryan Gavin, Microsoft’s general manager of search and Cortana, said in a Windows blog post announcing the change, “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.”
