Microsoft Extends M365 App Fixes on Windows 10 to 2028

Microsoft will continue delivering security updates for Microsoft 365 (M365) applications running on Windows 10 through 2028, extending support for its productivity suite even as the underlying operating system nears end-of-life. The announcement offers clarity for enterprise users relying on Windows 10 systems, though it highlights a growing divide between application and OS support.

While M365 apps will receive patches and vulnerability fixes for an additional three years, support for the Windows 10 operating system itself remains a separate matter. Microsoft previously confirmed that mainstream support for Windows 10 would end in 2025, raising concerns among corporate IT departments about managing legacy infrastructure.

The extended security coverage for M365 apps provides some relief for organizations yet to fully transition to Windows 11. However, without continued OS-level support, users may face increased risk from unpatched system components. Microsoft has not indicated any changes to its Windows 10 roadmap, leaving enterprises to weigh upgrade timelines carefully.
