In windows 10, if you open the start menu, type some search terms, and open a web search result, then until a few days ago, it used to open the search in your default browser. The same applied if you were using Cortana, and it didn't know the answer to your request.
However, Microsoft have changed this so these now open in the Edge browser, irrespective of which browser you have set as your default browser. Unfortunately, Edge is not accessible using Jaws or Window Eyes, though it is at least partially accessible using NVDA or narrator. This seems like a very surprising decision by microsoft, to make this change before Edge is accessible by users of all the major screen readers.
