The popup further tells the users that Microsoft Edge lets you write on webpages, has Cortana integration, and includes a reading view. This Microsoft move is likely to irk Google and Firefox  Mozilla CEO had blasted Microsoft earlier when the tech giant had made it harder to switch to Firefox in Windows 10, and the company even created a tutorial video to help Firefox users restore their default app settings. Microsoft appears to be doing the same for photo and music apps, too. If you attempt to switch defaults then a similar dialog box appears to try and convince you to stick with the built-in photos or Groove Music apps. Kindly note that earlier builds of Windows 10 dont have these popups and it is only seen in the new build which is expected to ship in the next few weeks. It is also possible that Microsoft could and will tweak exactly when and how this prompt appears. On a side note, despite Microsoft’s best of effort, the newly released Edge browser has not found the liking among Internet users.
