Microsoft introduced a new feature to Windows 10 called ‘News and Interests’ as part of the May 2021 Patch Tuesday updates. The feature is a taskbar news feed that displays the local forecast directly on your taskbar. When you click or hover your mouse, it opens up a screen showing news, sports scores, and stocks based upon your interests. If you are not a fan of the new widget, it is possible to disable it so that it does not appear on the Windows 10 taskbar.
