Microsoft has officially announced that support for the OneNote for Windows 10 app will end on October 14, 2025, marking the final chapter for one of its more peculiar software experiments. After this date, the app will enter a read-only state; users will still be able to view their notebooks, but editing, syncing, and updates will cease entirely. Migration prompts and in-app reminders have already begun rolling out, nudging users toward the modern OneNote on Windows app available via the Microsoft Store or bundled with Microsoft 365.
For years, Microsoft maintained two distinct OneNote apps for Windows:
- OneNote for Windows 10: A Universal Windows Platform (UWP) app, optimized for touch and bundled with Windows 10.
- OneNote (Desktop): The classic Win32 version, part of the Office suite and later rebranded as OneNote on Windows.
This dual-app strategy confused users and developers alike. The Windows 10 version was sleek, minimalist, and tightly integrated with the OS’s design language, but it lacked many advanced features found in the desktop version. Despite its UI and UX alignment with Windows 10, the app always felt like a half-step: modern in appearance, limited in capability.
Microsoft’s decision to sunset the UWP version reflects a broader retreat from its once-ambitious Universal Windows Platform strategy. Originally positioned as the future of Windows apps, UWP has quietly faded from prominence, leaving behind orphaned software like OneNote for Windows 10.
Microsoft is consolidating its efforts behind the modern OneNote on Windows app, which now supports Copilot-powered features, Group Policy customization, and faster development cycles. Users are encouraged to switch before October 2025 to avoid degraded performance. Sync speeds will slow starting in June 2025, and in-app migration banners will appear from July onward.
For enterprise IT teams, Microsoft has provided deployment guidance and WinGet packages to streamline the transition. And for everyday users, the switch is relatively painless: the new app is free, feature-rich, and already available on most systems.
The existence of a version-specific OneNote app, tied so closely to Windows 10’s aesthetic but not its longevity, was always a bit of a UX paradox. It looked like the future but behaved like a demo. Its retirement isn’t just a technical update; it’s a quiet acknowledgment that coherence matters more than branding. OneNote, like Windows itself, works best when it’s unified.
So if you’re still using OneNote for Windows 10, now’s the time to migrate. The notebooks will still be there, but the future of note-taking on Windows has officially moved on.
