Overview
- Microsoft will provide free security updates for Microsoft 365 Apps on Windows 10 until October 10, 2028, three years beyond the OS's end-of-support date.
- The extension aims to address security concerns for users unable to upgrade to Windows 11, including 240 million devices incompatible with the newer OS.
- Support for Microsoft 365 Apps on Windows 10 will not include logging bugs or requesting new product updates, and troubleshooting will be limited if issues do not occur on Windows 11.
- This policy shift was quietly implemented via updated support documentation and a Tech Community blog post, later confirmed by Microsoft.
- Windows 10's official support ends on October 14, 2025, with paid Extended Security Updates available for the OS, while Microsoft continues to push for Windows 11 adoption.
