Microsoft has quietly announced that it will cease adding new features to Microsoft 365 (Office) for Windows 10 users in August 2026. While security updates will continue until October 2028, functional enhancements will gradually be phased out starting next year, as reported by The Verge.

Users of Microsoft 365 Personal and Family will stop receiving new Office features on Windows 10 in August 2026, coinciding with the end of support for business users on the Current Channel. Following that, on October 13, 2026, new features will no longer be available to users on the Monthly Enterprise Channel, and on January 12, 2027, for those on the Semi-Annual Enterprise Channel.

Earlier this year, Microsoft had already abandoned its previous plan to fully discontinue security updates for Office on Windows 10, agreeing to extend them until 2028. However, at that time, the company did not indicate that new Office features would only be available on Windows 11 starting in 2026.

This is another step by Microsoft towards phasing out support for Windows 10, which will officially end on October 14, 2025. After that, Office updates will only consist of security patches without new functionality.

Despite Microsoft's strong encouragement for users to switch to Windows 11, millions of devices worldwide still operate on Windows 10. Even though Windows 11 recently surpassed Windows 10 in usage share for the first time, the transition is slow. Microsoft has offered home users the option to continue receiving security updates for free for an additional year if they activate the Windows Backup feature.
