The participants of the program testing Windows 10 Insider found a funny “innovation” in the latest test build of Windows 10. When you try to install third-party browser such as Chrome and Firefox, the operating system tries to “persuade” the user to do this.
When the installer is run the Chrome browser and Firefox POPs up a window that says the PC “there are already Microsoft Edge the most secure and fast browser for Windows 10” and offers two buttons “open Microsoft Edge” and “still set”. Also you can disable such warnings in the future.
The next major OS update, Windows 10 October 2018 Update should come out in October. It is unclear whether added this feature.
