Microsoft 365 Apps No Longer Supported on Windows 10 After 2025

In a move that underscores a significant shift in Microsoft's operating system strategy, the tech giant has officially announced that its popular Office apps, also known as Microsoft 365 apps, will cease receiving support for Windows 10 after October 14, 2025. While the headline might sound alarming at first, let's break this down into finer details and explain what this means for end users and businesses alike. Let’s also survey the broader implications of the decision.

The Big Announcement​

Microsoft recently confirmed in an official statement that October 14, 2025, marks the end of support for both Windows 10 and Microsoft 365 apps on the same day. This means that to continue official support for Office apps, users will need to migrate to Windows 11, which Microsoft has been heavily advocating for since its launch.
In its blog post, Microsoft emphasized that retirement of support is a crucial piece of its overall strategy to finally sunset Windows 10 and prioritize its newer operating system, Windows 11. This move aligns with the company’s plans to push innovation forward while reducing the maintenance burden of supporting legacy systems.

What Does ‘End of Support’ Mean?​

First, let’s clarify what Microsoft’s “end of support” label truly entails. Many users mistakenly assume that their Office apps will just stop working on October 14, 2025—but that’s not accurate.
According to Microsoft:

• The apps will continue to function on Windows 10 post-2025. There’s no digital guillotine waiting to cut them off.
• However, there will be no updates, which means no new features, no bug fixes, and, crucially, no security patches. Over time, this can result in increasing compatibility issues, performance hiccups, and elevated exposure to security vulnerabilities.

This creates an awkward situation for users and IT admins who might still rely on Windows 10 and value stability over switching to Windows 11.

Performance & Reliability Warnings​

Microsoft has warned users about “performance and reliability issues over time” if they choose to stay on Windows 10 with unsupported 365 apps. In simple terms, the longer you hold on to these unsupported configurations, the more potential headaches you’re likely to encounter.

Microsoft’s Windows 11 Push​

Labeling 2025 as the “Year of the Windows 11 PC Refresh,” Microsoft is ramping up its campaigns to migrate users to its newest OS. The company reiterated at CES 2025 that upgrading to Windows 11 isn’t just nice-to-have—it’s necessary.

Hardware Compatibility Hurdles​

However, there’s one pickle in this lofty goal: Windows 11’s strict hardware requirements. Millions of Windows 10 devices simply don’t meet the technical bar:

• TPM (Trusted Platform Module) 2.0: A security-related chipset feature that Microsoft refuses to compromise on.
• Processor generations: Only relatively modern processors are supported, leaving older but still functional devices behind.

Microsoft has repeatedly stood firm, calling the TPM 2.0 and other requirements “non-negotiable” for Windows 11 adoption. But this hard stance is one of the largest barriers to Windows 11 uptake, as countless devices fall short.

Temporary Security Insurance for Windows 10​

To soften the blow, Microsoft is offering Extended Security Updates (ESUs) for Windows 10 users who aren’t ready to jump ship. These updates are available at a cost:

• For individuals or small businesses, $30 per year extends security support for one year.
• Larger enterprises can purchase extended support for up to three years under custom plans.

This is an unprecedented step, as extended security updates have typically been targeted only at enterprise customers in the past.

Why This Matters to You​

If you’re a Windows 10 user running Office apps, you’re probably asking yourself: Should I care?

For Everyday Users:​

• Short-Term: Office apps like Word, Excel, and Teams will still work after October 2025, so there’s no immediate urgency to switch to Windows 11.
• Long-Term: Over time, you’ll have to contend with increasing risks. Unsupported apps are prime targets for hackers, especially as critical vulnerabilities remain unpatched.

For Businesses:​

• Enterprises rely on Office apps for mission-critical functions. Running unsupported software could expose sensitive data to breaches.
• Migrations to Windows 11 should ideally begin now to ensure a smooth, well-planned transition.
• The cost of ESUs for Windows 10 might be viable temporarily, but it’s not a long-term solution.

The Elephant in the Room: Windows 11’s Adoption Woes​

As much as Microsoft champions Windows 11 as its golden child, users remain skeptical. Adoption numbers suggest that Windows 11 struggles to match the overwhelming success of Windows 10. The culprit? You guessed it: those hardware restrictions.
Initially, there were murmurs of outrage from Windows enthusiasts, frustrated to learn that perfectly functional PCs couldn’t meet Windows 11 requirements. The issue persists today. Whether it’s TPM 2.0 or faster processors, Microsoft has drawn a hard line. Meanwhile, competitors like Linux or macOS gain underserved momentum simply because frustrated Windows users are exploring alternatives.

Will Microsoft’s Strategy Backfire?​

While Microsoft’s stance reflects a bold move to modernize its ecosystem, the strategy carries potential risks:

• Consumer Backlash: Users accustomed to decade-long support lifecycles may find the rapid push to upgrade off-putting. (Remember the Windows 11 “forced upgrade” social media uproar from 2023?)
• Loss of Market Share: Persistent strictness around hardware requirements—especially when global hardware shortages remain an issue—could push users toward other platforms.

That said, Microsoft has historically excelled at weathering rocky transitions. Windows XP users were slow to move to Windows 7, and Windows 8 was equally divisive, but eventually, everyone came around. Will history repeat itself? Time will tell.

Final Thoughts: What Should You Do Now?​

Step-by-Step Recommendations​

• Audit Your System:
• Is your hardware Windows 11-compatible? If yes, bookmark a time to upgrade.
• If your PC isn’t ready for Windows 11, consider alternatives like ESU support or planning for a new machine.
• Using Microsoft 365 Apps?
• Be aware that while functional, unsupported apps can’t guarantee performance, reliability, or security. Don’t delay upgrades indefinitely.
• Budget for an Update:
• Whether migrating to Windows 11 or purchasing ESUs, have a clear financial plan.
