On October 14, 2025, Microsoft will end support for "OneNote for Windows 10 (legacy)," which will then transition to read-only mode, preventing users from editing or synchronizing notes. Users are encouraged to migrate to the newer OneNote app for Windows 11 to maintain editing capabilities. To transition, users must sync their notebooks to a OneDrive account and can use an in-app migration feature. Microsoft is notifying users about this change through an in-app banner. The legacy app currently has a user rating of 4.6 in the Microsoft Store.
