Microsoft is making its position on Windows 10 increasingly clear. According to an updated support page published by Microsoft, the company will halt all new feature development for Microsoft 365 Apps on Windows 10 after the August 2026 release. Once Version 2608 rolls out, the Office suite will enter a maintenance-only phase, receiving security patches but no functional upgrades or Copilot integration. This shift aligns with Microsoft’s broader strategy to consolidate its user base on Windows 11, but it leaves a significant number of enterprise and home users with a hard deadline to evaluate their hardware and software readiness.
What exactly is changing
The core of the announcement centers on Version 2608, which Microsoft expects to deploy this month. As noted in the official support documentation, devices running Microsoft 365 Apps on Windows 10 will receive feature updates and Copilot support until that version ships. After Version 2608 is installed, the feature set becomes frozen. You will continue to use the same Word, Excel, PowerPoint, and Outlook capabilities that were available in the 2608 build, but any subsequent innovations will not be pushed to Windows 10 machines.
This freeze is a deliberate policy shift rather than a technical limitation. Microsoft has historically extended Windows 10 compatibility for its productivity apps to ease the transition, but the company is now drawing a firm line. The support page explicitly states that after Version 2608, Windows 10 devices will remain on that exact version while receiving only security updates until October 10, 2028. Once that date passes, both feature and security updates will cease entirely, leaving the software in a static and increasingly vulnerable state.
The support timeline for Office and OneDrive
The cutoff dates apply differently depending on which Microsoft 365 component you are using. For the core Office applications, the timeline is straightforward: feature updates stop after Version 2608, and the entire support lifecycle ends on October 10, 2028. This gives users roughly two and a half years of security-only maintenance before the software is completely unsupported.
OneDrive follows a slightly more nuanced path. Microsoft confirmed that the OneDrive desktop app will continue to receive updates through October 10, 2028, but only on devices running Windows 10 22H2. If you are operating on an older Windows 10 build, the OneDrive desktop client will stop updating immediately once the broader Office freeze takes effect. This distinction matters for users who rely on OneDrive for file synchronization, version history, and selective sync features, as older builds will gradually lose access to bug fixes and performance improvements.
What this means for you
For everyday users, the immediate impact is minimal. You will continue to use Microsoft 365 on Windows 10 without interruption, and your existing subscription will remain fully active. However, the long-term implications are worth understanding. Microsoft explicitly warns that continuing to run Microsoft 365 Apps on an unsupported operating system can cause performance and reliability issues. In practice, this means you may encounter slower application launch times, increased memory usage, or sync failures as the Office suite optimizes for Windows 11 architecture while leaving Windows 10 behind.
Enterprise administrators should pay closer attention to the October 2028 deadline. When security updates stop, your Windows 10 machines running Microsoft 365 will become non-compliant with most modern IT security policies. Organizations that have not yet completed their Windows 11 migration will need to accelerate their rollout plans or consider alternative licensing models that support legacy environments.
How to prepare for the transition
The most reliable path forward is upgrading to Windows 11. Microsoft has kept the upgrade path open for eligible Windows 10 devices, and the transition is largely free for users with a valid license. Before initiating the upgrade, verify that your hardware meets the TPM 2.0 and Secure Boot requirements, as these are non-negotiable for Windows 11 compatibility. If your current PC fails the PC Health Check app, you may need to plan a hardware refresh sooner rather than later.
For users who cannot upgrade immediately, there are temporary workarounds. You can continue using the current version of Microsoft 365 on Windows 10 until Version 2608 rolls out, and you will still receive security patches until October 2028. However, relying on this window indefinitely is not advisable. Start by backing up your Office templates, custom dictionaries, and OneDrive configurations, then test the Windows 11 upgrade on a secondary device if possible. The sooner you migrate, the less you will miss from the evolving Office ecosystem.
