What Happens When Windows 10 Office Support Ends?
Microsoft has officially announced the end of support for Windows 10 on October 14, 2025. For users still relying on Office apps installed on Windows 10, this raises a crucial question: Will your Office apps continue to work?
The short answer: Not safely. With Microsoft shifting focus toward Office 2025 and Windows 11, it’s time to consider upgrading. In this blog, we’ll break down the implications of this change, what users can expect from Office 2025, and how it pairs with Windows 11 for optimal performance.
What Does End of Support Mean for Office Apps on Windows 10?
When Microsoft ends support for an OS or application, it stops delivering security updates, bug fixes, and customer support. This leaves users exposed to vulnerabilities and incompatibility issues.
Key Impacts After October 14, 2025:
- No security patches for Office apps running on Windows 10.
- Compliance risks for business environments.
- Limited access to new features or updates.
- Incompatibility issues with newer software releases.
Recommendation: Migrate to a supported system (Windows 11 + Office 2021 or Office 2025) before the deadline.
What’s New in Office 2025?
Office 2025 is the next perpetual version from Microsoft, designed to work seamlessly with Windows 11. Unlike Microsoft 365, it’s a one-time purchase with long-term support.
Top Features of Office 2025:
- AI-Driven Tools – Smarter Excel formulas, real-time document suggestions, and intelligent writing assistance.
- Cloud Integration – Improved OneDrive syncing, real-time co-authoring even without Microsoft 365 subscription.
- Optimized for Windows 11 – Faster load times, touch-screen enhancements, and better UI scaling.
Why Pair Office 2025 with Windows 11?
Office 2025 is optimized to run on Windows 11, not Windows 10. Using both ensures:
- Maximum performance
- Better stability
- Ongoing support and updates
- Access to the latest productivity tools
Many users who try running Office 2025 on Windows 10 may experience limited functionality or setup errors.
