How Long Will Microsoft 365 Apps Stay Secure on Windows 10? Key Dates You Can’t Ignore

Is Your Data at Risk? Discover the Vital Ending Dates for Microsoft 365 Support on Windows 10

Microsoft will stop regular support for Windows 10 on October 14, 2025. This means the system will not get typical security fixes after that date. Microsoft suggests switching to Windows 11 for the best safety. But there are still ways to keep your devices safe for a while longer if you need more time.

What Stays Updated—And For How Long?

Microsoft 365 Apps on Windows 10

Feature updates (new tools or improvements) will continue until version 2608 is released. After version 2608, no more new features, but apps will still work and get important security updates.

Key Dates for the Last Feature Updates

  • Current Channel (Home, Family): August 2026
  • Monthly Enterprise Channel: October 13, 2026
  • Semi-Annual Enterprise Channel: January 12, 2027

Security Updates

These will continue for Microsoft 365 Apps on Windows 10 until October 10, 2028. This keeps your software protected from new risks, even without new features.

Extended Security Updates (ESU) Program

  • Regular users can join the ESU program for one extra year of security updates (until October 13, 2026).
  • Companies can get up to three more years of security updates—until October 10, 2028.
  • Special Long-Term Servicing Channel (LTSC) versions can receive security updates until 2031.
  • ESU updates only cover security fixes, not new features or general enhancements.

How Will Support Work?

If you have a problem with Microsoft 365 Apps on Windows 10 after October 14, 2025, you can still ask for help if you have a valid Microsoft 365 subscription.

If the issue only affects Windows 10, Microsoft will suggest moving to Windows 11. If you cannot, they will help with troubleshooting, but fixes may be limited.

What About Windows Server 2016 and 2019?

End Date

Microsoft 365 Apps support ends on October 14, 2025, for these server versions, just like Windows 10.

Feature Updates

Server 2016 and 2019 will get feature updates up to version 2608 on these dates:

  • Current Channel: February 2026 (Server 2016), August 2026 (Server 2019)
  • Monthly Enterprise: April 14, 2026 (Server 2016), October 13, 2026 (Server 2019)
  • Semi-Annual Enterprise: July 14, 2026 (Server 2016), January 12, 2027 (Server 2019)

Security Updates

These will be provided up to October 10, 2028, for version 2608.

Key Takeaways

Feature updates for Microsoft 365 apps on Windows 10 stop with version 2608 on different dates in 2026/2027, depending on your update channel.

Security updates will be available for all users until October 10, 2028, offering vital protection.

Support cases are still allowed if you have a valid Microsoft 365 subscription, but direct fixes or enhancements may not be available if you cannot switch to Windows 11.

ESU programs exist for both individuals and companies to help keep devices safe during the transition.

Tips for a Safer and Smoother Transition

  • Plan to upgrade to Windows 11 before or soon after October 2025.
  • Keep track of update channels and mark important cutoff dates in your calendar.
  • For companies, consider joining ESU early to avoid last-minute problems.
  • For home users, remember ESU gives only one more year, so act early.

This extended support with security updates means more peace of mind through the upgrade period. Delays in updating bring risks, so use the extra time wisely to get your devices ready for future needs.
