According to Windows Latest, “Microsoft is A/B testing a new feature that is designed to nag users with fullscreen window-less Microsoft Edge recommendations in the OOBE screen.” From the report: The nag will appear when users set up their PC, sign in to their system after applying updates, or when they click on a new ad banner within the Settings. […] Microsoft is trying to convince users of rival browsers who are visiting Windows Settings of the benefits of trying the Chromium Edge. In the Settings app, there’s a new banner that appears to be rolling out to non-Insiders. As you can see in the above screenshot, the advert appears across the top of the Settings app window, just above the settings options. The banner states that you can “get even more out of Windows” and it surprisingly launches the OOBE (out of the box experience) screen. […] This ad appeared only when our devices were set to use Google Chrome and Firefox as the default web browser. The user can easily close the advert by clicking the second option “Don’t update your browser settings.” If you try to skip the setup, the pop-up will appear again in future. Unfortunately, you cannot permanently disable these recommendations in Windows 10.
