Microsoft has announced the discontinuation of "OneNote for Windows 10," encouraging users to transition to the new OneNote app designed for Windows 11. The legacy app will have its sync speed throttled starting in June 2025, with end of support set for October 2025. Microsoft has removed the older app from the Microsoft Store and advised enterprise customers to switch to the new version available through the Microsoft Store or a Microsoft 365 subscription. Users of the legacy app will receive prompts to migrate to the modern OneNote by July 2025. The new version offers enhanced security, AI capabilities, and improved performance but lacks some features of the legacy app.
