Why Microsoft Is Ending Support for OneNote for Windows 10
Microsoft has long been dedicated to enhancing its application ecosystem. As part of this vision, the popular OneNote for Windows 10 will no longer receive support after October 14, 2025. In a move aimed at centralizing and modernizing the user experience, this decision mirrors Microsoft’s broader shift towards a unified OneNote app available across all supported Windows platforms. Most importantly, this transition brings about improved security protocols and a sustainable roadmap for future innovations.
Because technology continuously evolves, Microsoft’s focus on a modern app ensures that users benefit from increased efficiency and robust functionality. Therefore, by retiring the older version, Microsoft paves the way for a system that integrates advanced collaboration tools, enhanced security measures, and a host of new features that demand regular updates and support. Besides that, the upgrade reflects a commitment to keeping users at the cutting edge of digital note-taking and productivity enhancements.
Implications for End Users and Organizations
The upcoming end of support carries significant implications for both individual users and organizations. After October 14, 2025, the OneNote for Windows 10 app will switch to a read-only mode, meaning users can only view their existing notes. This limitation emphasizes the need to transition to the new OneNote app, as continued editing, syncing, and creation of new notes will be halted. Because of this change, users must start planning their migration imminently, especially if they depend heavily on the app for day-to-day tasks.
In addition, relying on an unsupported application exposes both personal and organizational data to security vulnerabilities. Most notably, no further updates, bug fixes, or security patches will be provided. This shift could lead to compatibility issues and potential data loss, particularly for enterprise environments where collaboration and real-time updates are essential. Consequently, businesses are strongly encouraged to initiate the migration process well before the deadline to ensure that workflows remain uninterrupted and secure.[3]
Exploring the New OneNote on Windows Experience
Transitioning to the modern OneNote on Windows (often referred to as OneNote M365 or the desktop version) offers distinct advantages. For instance, the modern app provides continuous updates that include AI-powered productivity tools like Copilot, which not only boost efficiency but also ensure that note-taking remains intuitive and versatile. Additionally, the revamped interface is designed for faster syncing and real-time collaboration, making it suitable for both individual users and large organizations.
Moreover, the new OneNote offers enhanced security features that align with the latest Microsoft Information Protection (MIP) standards. Because the application is integrated with advanced compliance mechanisms, it supports a spectrum of sensitivity labeling and data protection policies, critical for secure business operations. Therefore, users transitioning to the new platform will enjoy unparalleled support and an extensive range of modern features tailored for today’s digital challenges.
Migration Timeline and Action Steps
Microsoft recommends a proactive approach to migration to help users avoid last-minute complications. Initially, by January 2025, in-app notifications will start alerting users about the upcoming end-of-support deadlines. These notifications serve as an early warning, allowing ample time to plan and execute the transition. Most importantly, these alerts provide direct links to requirements and troubleshooting guides, which users can access for assistance.[4]
Furthermore, persistent banners will appear by July 2025 to remind users to switch to the modern app. Because this timeline is designed to minimize interruption, it ensures that enterprises and individuals have enough time to migrate and test new functionalities. Additionally, organizations managing multiple devices can benefit from Microsoft’s detailed OneNote deployment guide and official migration scripts, ensuring that the transition is as seamless as possible. Ultimately, from October 14, 2025, the old app will be rendered read-only, urging everyone to have fully transitioned beforehand.[3]
Key Differences: OneNote for Windows 10 vs. OneNote on Windows
The differences between the legacy OneNote for Windows 10 and the modern OneNote on Windows are substantial. For example, while the older version will become read-only after the cutoff date, the modern version offers full editing capabilities and ongoing feature enhancements. Moreover, users switching to the new app will enjoy regular security updates and integration with advanced tools like AI-driven Copilot for more efficient note management.
Additionally, the new OneNote app is designed to work with Microsoft 365 and is available on the Microsoft Store for free. Besides that, it includes features such as faster syncing and enhanced data compliance with MIP, which provides an essential layer of security for business users. These improvements underscore the importance of transitioning sooner rather than later to leverage a robust set of features that strengthen productivity and security.

Frequently Asked Questions
Can I keep using OneNote for Windows 10 after October 2025?
While you are permitted to view your existing notes, you will not be able to create, edit, or sync new content in OneNote for Windows 10 after October 2025. Because continued use in a read-only state limits productivity, it is highly recommended to switch to the updated version promptly.[3]
Most importantly, switching not only retains your editing privileges but also secures your data with the latest protection features. Therefore, upgrading is essential for anyone who relies on the tool for dynamic note-taking and team collaboration.
Is the new OneNote on Windows free?
Yes, the modern OneNote app is freely available via the Microsoft Store and comes bundled with Office and Microsoft 365 subscriptions. Because this makes the transition convenient and affordable, it has been widely adopted across various user segments.
Additionally, some advanced features in the modern OneNote may require a subscription. However, for most users, the free version still offers significant enhancements over the old app, ensuring that everyone can maintain productivity without extra costs.
Will my existing notebooks and data migrate automatically?
Fortunately, your cloud-based notebooks will automatically sync once you sign into the new OneNote application. Most notably, the migration process is streamlined for users who store data in Microsoft’s cloud, guaranteeing that your notes and files are accessible immediately after the switch.
However, for local notebooks saved on your device, additional migration steps might be necessary. Therefore, consulting Microsoft’s detailed OneNote deployment guide is strongly recommended to avoid any loss of information during the transition.
Conclusion: How to Prepare for October 2025
Microsoft’s decision to end support for OneNote for Windows 10 is part of a broader modernization strategy designed to optimize productivity and security. Most importantly, users are encouraged to transition to the modern OneNote on Windows to continue benefiting from full functionality and ongoing updates. Because the change is irrevocable, starting your migration as soon as possible is critical.
Furthermore, with ample time to adapt through in-app notifications and supportive tutorials, this transition will be smooth. Organizations and individual users alike should take proactive steps now to secure their data, enjoy the latest features, and ensure seamless integration with the continuously evolving Microsoft ecosystem.
