Microsoft to end support for Office 365 Apps on Windows 10

Written by Lawrence Taylor-Ayres | 10/02/25 09:00

In a recent announcement, Microsoft revealed that it will stop supporting Office 365 apps on Windows 10 on 14th October 2025 – clarifying that Windows 10 end-of-life on the same date will also have ramifications for Office 365. This change could have significant implications for businesses still running older versions of Windows, especially those relying on Office 365 tools for daily operations.

Why the Change?

Microsoft’s move is part of a broader push to encourage businesses to upgrade to Windows 11. The decision aligns with their strategy to streamline support and ensure better performance and security for users. As security patches and feature updates will no longer be available for Office apps on Windows 10, businesses should seriously consider updating their systems to avoid potential vulnerabilities and disruptions.

What This Means for Your Business:

  1. Security Concerns: Without ongoing support and updates, your business could be exposed to cyber risks.
  2. Reduced Functionality: New Office 365 features may not be compatible with Windows 10 after support ends, potentially limiting productivity.
  3. Time to Upgrade: If you’re still on Windows 10, now is the time to plan your transition to Windows 11. This will ensure your teams have access to the latest features and security patches. As there is now a confirmed date for the end of support, disruption is almost a guarantee if you leave upgrades to the last minute.
