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.
