- Product
- Microsoft OneNote
- Device & OS
- Windows 11
- Scenario
- Launching or updating the OneNote application on a Windows 11 computer.
- Observed behavior

Repair Microsoft 365 via Windows Settings
Use the built-in Windows repair tool to fix underlying installation issues with Microsoft 365 that cause version conflicts.
Often, version reverting occurs because of a corrupted Microsoft 365 installation. Running the built-in repair tool can fix these core files without needing a complete reinstall.
Press the Windows key + I on your keyboard to open the Settings app, then click on 'Apps' in the left-hand menu and select 'Installed apps'.
Scroll through the list of installed applications or use the search bar at the top to find 'Microsoft 365' or your specific Office edition.
Click the three horizontal dots next to the Microsoft 365 entry and select 'Modify'. If prompted by User Account Control, click 'Yes'.
Select 'Online Repair' for a comprehensive fix (requires an internet connection) and click 'Repair'. Follow the on-screen instructions.
Once the repair process is complete, restart your Windows 11 PC and open OneNote to ensure the correct, updated version is running.

Identify and Remove Conflicting Versions
Windows 11 may have both the new desktop OneNote and the older discontinued 'OneNote for Windows 10' installed, causing system confusion.
Try WPS Office for a Hassle-Free Productivity Experience
If Microsoft 365 continues to experience installation conflicts and version rollbacks on Windows 11, consider switching to WPS Office. It provides a highly stable, lightweight, and completely free alternative for your document and note-taking needs.

Frequently Asked Questions
Why are there two different versions of OneNote on Windows 11?
Historically, Microsoft provided a desktop version bundled with Office and a UWP app called 'OneNote for Windows 10'. Both might be installed on your system if you upgraded from Windows 10, leading to confusion over which version is active.
Will I lose my notes if I completely reinstall Microsoft 365?
No, as long as your notes are successfully synced to your Microsoft OneDrive account, they are safely stored in the cloud. They will automatically download and reappear once you sign in to the freshly installed app.
What is the difference between Quick Repair and Online Repair for Office?
Quick Repair checks and replaces corrupted files locally without needing an internet connection. Online Repair is a more thorough process that uninstalls and completely re-downloads the latest Microsoft 365 application files.
What should I do if the Windows Settings repair fails?
If the built-in Windows repair tool fails, you can download the Microsoft Support and Recovery Assistant (SaRA) from the official Microsoft website to completely uninstall and reinstall the Office suite.
