Microsoft Corp., which is unveiling a new version of Windows for the first time in six years, said it will integrate its Teams chat and videoconferencing software directly into the operating system.

Teams has seen a huge surge in users during the pandemic, boosting Microsoft in a product category where it’s been trying to catch up with Slack and Zoom. The latest personal computer operating system, Windows 11, also features a new design and will offer changes to the app store.
