Microsoft 365 Apps to Lose Windows 10 Support: What You Need to Know

It's official — starting October 14, 2025, Microsoft will no longer offer support for Microsoft 365 apps, such as Word, Excel, and PowerPoint, on Windows 10. This announcement coincides with the end of support for the Windows 10 operating system itself. Although this news might seem like just another tech company policy shift, this change has significant implications for users, particularly those heavily reliant on Microsoft's ecosystem for productivity and day-to-day operations. Let’s break down what’s happening, explore what it means for every day users, and discuss how you can navigate the impending changes.

What Happens After October 14, 2025?​

Here’s the headline: on October 14, 2025, Microsoft 365 apps running on Windows 10 will lose access to critical updates. This includes:

• Security Updates: Any vulnerabilities found in Word, Excel, PowerPoint, or other Microsoft 365 apps won't be patched.
• New or Updated Features: No fresh features or functionality improvements for Office apps on Windows 10.
• Technical Support: If you encounter an issue running Microsoft apps on your aging Windows 10 system, you’re on your own — Microsoft will no longer offer troubleshooting assistance.

The apps themselves won't stop working. You’ll still be able to fire them up and use them as-is after the support ends. However, you'll essentially be sitting on what cybersecurity experts often refer to as a “ticking time bomb.” No patches for vulnerabilities mean your system becomes progressively easier for bad actors to exploit, leaving your personal data and files at risk.

The Nudge Towards Windows 11: Free Upgrades (For Some)​

From Microsoft’s perspective, encouraging users to upgrade to Windows 11 is a no-brainer. According to the announcement, upgrading to Windows 11 will be free for users meeting the hardware specifications. Microsoft has made lofty promises about Windows 11, emphasizing its more robust security frameworks, sleeker interface, and modernized tools.
For many users, this "free upgrade" comes with a caveat. Your hardware must meet these minimum requirements to upgrade to Windows 11:

• A compatible 64-bit processor with at least 1GHz or multiple cores,
• 4GB of RAM or more,
• A minimum of 64GB storage,
• TPM 2.0 (Trusted Platform Module) support,
• A DirectX 12 compatible graphics card.

You may recall the hardware requirements for Windows 11 stirred up significant controversy during its launch. Older PCs — even some relatively modern systems — were excluded from upgrading because they lacked hardware-based security features like TPM 2.0. If your device doesn’t meet these specs, you won’t get the free ride to Windows 11, leaving you with fewer options as Microsoft's updates stop rolling in.

The Alternatives: Pay Up or Switch Strategies​

For users who aren't interested or eligible to upgrade to Windows 11, Microsoft has a couple of paths forward:

1. Microsoft 365 on the Web​

This option might sound like a silver lining. Microsoft emphasizes that Office on the Web remains free, enabling users to work on Word, Excel, and PowerPoint through a browser like Edge or Chrome. All you need is an internet connection (and patience for browser-based apps). However, it’s worth noting:

• It lacks certain premium features found in the desktop versions.
• You’ll need consistent internet access, which could be limiting for offline environments.
• Performance depends heavily on the speed and reliability of your browser.

Who’s this ideal for? Casual users who only need basic word processing and spreadsheet tools on occasion.

2. Extended Security Updates (ESU) Program​

Microsoft is offering a band-aid solution in the form of its Extended Security Update (ESU) Program, available for an annual fee. As of this announcement, home users will be charged $30/year for critical security patches. While it's definitely cheaper than replacing your PC, this band-aid solution is temporary.

• It’s essentially designed for IT departments managing large fleets of older hardware, giving them a longer runway to transition their systems.
• For individuals, the cost and limited lifespan (ESU programs historically only last three years) may not be worth it.

Why Microsoft Is Moving On​

This transition aligns with Microsoft's larger strategy of steering users toward Windows 11 and its subscription-based ecosystem. Here’s why this makes sense for them:

• Enhanced Security: Microsoft admits that Windows 10 is less secure by modern standards. Without a switch to newer OS versions, the risk of widespread vulnerabilities increases.
• Simplified Product Ecosystem: Maintaining operating systems and apps across multiple generations is costly. By sunsetting older products, Microsoft directs its resources into innovation within Windows 11 and beyond.
• Push for Cloud Synergy: The free access to Office on the Web underscores Microsoft’s larger push toward cloud computing. They want you working in OneDrive, accessing tools online, and gradually untethering from local desktop installs.

How to Prepare for the Transition​

If you’re still clinging to Windows 10 and Microsoft 365 apps, don’t panic. Here’s a simple roadmap to navigate the change:

1. Audit Your Hardware​

• Verify whether your PC meets Windows 11’s requirements using the PC Health Check Tool (available on the Microsoft website).
• If it does, upgrading can extend the lifespan of your device—and it’s free!

2. Explore Open Source and Alternatives​

For those unwilling or unable to upgrade, now is a great time to explore non-Microsoft alternatives like LibreOffice or Google Workspace.

• LibreOffice: An open-source, robust Office suite similar to Microsoft Office.
• Google Workspace: If you’re already tied to Gmail and Google Drive, think about transitioning completely into their productivity ecosystem.

3. Upgrade Your Device​

Let’s face it: if your hardware is over 5–7 years old, it’s time to consider upgrading. Modern PCs come with built-in enhancements like SSDs, advanced processors, and better compatibility with Windows 11. Plus, if you're replacing your PC, it's a great opportunity to embrace forward-looking tech like hybrid workstations or gaming laptops.

Final Thoughts: The Clock Is Ticking​

Microsoft phasing out support for Microsoft 365 on Windows 10 marks a complex crossroad for users. Change is always daunting, but with a little planning, this transition could be an opportunity to upgrade your digital workspace for the better.
Whether you’re opting for Windows 11, relying on browser-based Office apps, or exploring free Office alternatives, there’s no shortage of choices. What remains certain is this: staying on Windows 10 past October 2025 is not a risk worth taking.
Now that you've read the breakdown, how are you planning to handle the shift? Will you upgrade to Windows 11 or explore alternative solutions? Let the discussion begin! Share your thoughts below!
