To uninstall OneNote for Windows 10, open Settings > Apps, find OneNote for Windows 10, click it, and choose Uninstall. Before you do, make sure your notebooks are synced, because OneNote for Windows 10 reached end of support on October 14, 2025 and Microsoft recommends moving to the current OneNote app. Notebooks stored in OneDrive stay safe when you uninstall the app.
