Question details
Understand the differences between OneNote 2016 and OneNote 2021, including Microsoft's naming conventions and application updates.

- Product
- Microsoft OneNote
- Device & OS
- Windows 10 and Windows 11
- Scenario
- Comparing desktop versions of Microsoft OneNote to clarify which application to use for note-taking.
- Observed behavior
- Users are confused by the version names, as OneNote 2016 was renamed to simply "OneNote" and is the same primary desktop application used in Microsoft 365 and newer Office releases, rather than a distinct "OneNote 2021" app.
Check your Windows Start menu to see which versions of OneNote are currently installed on your computer, as you may have both the classic desktop app and OneNote for Windows 10.
Understanding OneNote Version Changes
Learn how Microsoft updated the naming and functionality of the classic OneNote desktop application.
The primary difference lies in the naming convention rather than the software being a completely different program. OneNote 2016 was the classic desktop version included with Office 2016.
In 2019, Microsoft dropped the year from the name. The application is now simply called "OneNote." It continues to receive updates and is the default version included with Microsoft 365 and Office 2021 subscriptions.
Click the Start button on your Windows 10 or Windows 11 taskbar.
Type "OneNote" into the search bar. If you see an app named just "OneNote", this is the updated continuation of OneNote 2016.
Open the "OneNote" application, click on "File" in the top left corner, and select "Account" to view your current build and license information.

Changing the Default OneNote Application in Windows
Set your preferred OneNote version as the default application for opening notebooks and taking quick notes.

Frequently Asked Questions
Does Microsoft 365 include OneNote 2021?
Microsoft 365 includes the unified desktop application simply named "OneNote". It does not use the "2021" year designation, but it contains all the latest features and updates.
Can I still run OneNote 2016 on Windows 11?
Yes. The desktop app originally known as OneNote 2016 (now called OneNote) is fully supported on Windows 11 and continues to receive security and feature updates.
Why does my app just say "OneNote" without a year?
In 2019, Microsoft decided to drop the year from the application's name. If your app is just called "OneNote", you are using the primary, most up-to-date desktop version.
What will happen to OneNote for Windows 10?
Microsoft is consolidating its OneNote apps. OneNote for Windows 10 is no longer receiving new features and users are encouraged to migrate to the main "OneNote" desktop application.
