Microsoft has taken another step in its long-term plan to phase out Windows 10 by gradually limiting the support it provides to users of Microsoft 365 apps — formerly known as Office 365 — who continue to use the older operating system. The latest change focuses on clarifying how updates will work for these apps moving forward, and it underscores Microsoft’s larger goal: encouraging users to upgrade to Windows 11.
The End is Near — For Both Windows 10 and Microsoft 365 Apps
It’s no surprise that Windows 10 is nearing the end of its support lifecycle. Microsoft has been warning users for years that official support for Windows 10 will end on October 14, 2025. That means after that date, the operating system will no longer receive security patches, bug fixes, or new features.
What’s more notable — and perhaps more impactful for everyday users — is that Microsoft 365 apps like Word, Excel, PowerPoint, and Outlook will also stop receiving support on Windows 10 on that same day.
This doesn’t mean the apps will stop working entirely. Users will still be able to open and use Microsoft 365 applications after October 2025, but with some significant limitations. Microsoft has committed to providing security updates only for Microsoft 365 apps on Windows 10 for three years after support ends — that is, through October 10, 2028.
What’s the Catch?
The key detail in Microsoft’s latest update is the distinction between security updates and feature updates. Microsoft has clarified that once support for feature updates ends, Microsoft 365 apps on Windows 10 will stop receiving any new tools, improvements, or integrations — particularly those powered by artificial intelligence, such as Copilot.
Here’s how the timeline breaks down:
- Feature updates for Microsoft 365 apps on Windows 10 will continue only until the release of Version 2608, which is scheduled for August 2026 for the Current Channel — this includes both consumer and business versions.
- After Version 2608, Microsoft 365 apps on Windows 10 will no longer receive new features.
- From August 2026 to October 2028, the apps will be locked into that version and receive only security patches.
This is a subtle but important shift. While users can technically continue using Microsoft 365 on Windows 10 for a few more years, they’ll be missing out on new innovations — many of which are increasingly focused on productivity-enhancing AI tools.
A Gentle Push for Users — or a Firm Nudge?
Microsoft’s move can be seen as part of a broader strategy to drive adoption of Windows 11. While the company isn’t outright forcing users to switch, it’s creating a clear incentive structure: If you want the latest Microsoft 365 features, you’ll need to be on a supported operating system — namely, Windows 11.
With Microsoft increasingly integrating AI capabilities into its productivity suite — from smart email writing suggestions in Outlook to real-time Excel insights powered by Copilot — users who stick with Windows 10 may find themselves falling behind in both functionality and efficiency.
The strategy walks a fine line between support and persuasion. On one hand, Microsoft is giving users a generous runway with three additional years of security updates. On the other hand, the message is clear: if you want the whole Microsoft 365 experience, you need to move to Windows 11.
What Users Should Do
If you’re currently using Windows 10 and rely on Microsoft 365 apps, it’s time to start planning your next steps. For many businesses and individuals, upgrading to Windows 11 will be the most straightforward path. However, this also depends on whether their existing hardware supports the newer operating system, which has more stringent requirements than Windows 10.
Alternatively, some organizations may choose to stick with Windows 10 and accept the limitations, especially if they prioritize system stability over access to cutting-edge features.
In either case, the clock is ticking. October 2025 marks a significant transition point not only for Windows 10, but also for the entire Microsoft productivity ecosystem.
