Microsoft continues to maintain several versions of its note-taking application, OneNote, though the company has previously announced that it will permanently retire OneNote for Windows 10, the version built on the UWP framework.
According to Microsoft’s latest support advisory, beginning October 14, 2025, the UWP edition of OneNote will be switched to read-only mode. This means users will still be able to sign in and view synchronized data but will no longer have the ability to edit or create new content.
For those wishing to continue editing notes, creating new entries, and syncing data within OneNote, an upgrade to the new version of OneNote is required. Determining which version you are currently using is simple: open OneNote and check the upper-left corner. If a File tab is visible, you are on the new version. If the tab is absent, you are using the UWP edition, which must be replaced with the updated version. The older version can then be uninstalled once migration is complete.
With regard to synchronization, issues may arise if multiple accounts are configured. Microsoft instructs users to select “Sync Now” for each notebook and account individually. If any synchronization errors occur, they must be resolved prior to uninstalling the older version.
Once synchronization is complete, users should verify within the new OneNote that all data has been successfully transferred. After confirming, the UWP version can be safely removed. The new OneNote can be downloaded directly from onenote.com by clicking the Download button in the upper-right corner.
