Microsoft says that it will be an ad-free feature, and that you can still disable it if you don’t like seeing it. Making use of it will first require the installation of the new Chromium-based Edge browser. Which shouldn’t be a problem as it’s something that’s rolled out via a previous Windows update. But it also means clicking on any articles will open them in the Edge browser.
As mentioned, the new Windows 10 Taskbar is now only available to testers. And specifically, only to those in the US, UK, Canada, Australia and India. No specific date as to when it will roll out to general users just yet.
