Microsoft Extends Office App Security Updates on Windows 10 Through 2028

Microsoft has announced a significant extension to its support for Microsoft 365 Office applications on Windows 10, now promising security updates until October 10, 2028. This extension adds three more years beyond the previously stated end-of-support date of October 14, 2025, providing critical security maintenance for users who have yet to transition to Windows 11.

Originally, Microsoft had planned to cease support for Microsoft 365 apps on Windows 10 after the 2025 cutoff, encouraging users and businesses to upgrade to Windows 11 to ensure continued functionality and performance. However, the company has revised this stance, acknowledging the need for a smoother transition period by maintaining security updates for an additional three years.

These updates will be delivered through the standard Microsoft update channels, ensuring that Microsoft 365 apps continue to function securely on Windows 10 devices. Microsoft advises businesses to plan their migration to Windows 11 to avoid potential performance and reliability issues that may arise over time as support phases out.

For organizations and consumers who are unable or unwilling to upgrade immediately, Microsoft also offers Extended Security Updates (ESU) for Windows 10. Consumers can purchase an additional year of updates for $30, while businesses have the option to buy up to three years of extended updates, providing further flexibility in managing their IT environments.

This extension reflects Microsoft’s recognition of the challenges many organizations face in migrating to new operating systems and the importance of maintaining security during transitional periods. It also underscores the company’s commitment to supporting its vast Windows 10 user base while encouraging gradual adoption of Windows 11.

Implications for Businesses and IT Leaders

For IT departments, this extension provides a valuable window to plan and execute OS upgrades without compromising security. It reduces the urgency to rush migrations, allowing for thorough testing and training. However, it also means maintaining dual support environments longer, which can impact resource allocation and budget planning.

Organizations should leverage this period to evaluate their infrastructure, update security policies, and prepare end-users for the transition to Windows 11. Staying informed about Microsoft’s update schedules and support policies will be critical to maintaining operational continuity and security compliance.

Conclusion

Microsoft’s decision to extend Microsoft 365 app security updates on Windows 10 until 2028 offers a pragmatic solution for users navigating the complexities of OS upgrades. It balances the need for security with the realities of enterprise IT management, providing a safety net during the transition to Windows 11. Businesses and consumers alike should use this extension period strategically to ensure a smooth, secure migration.
