Lots of hard work has been put in to unify OneNote and OneNote for Windows 10. I get asked this question a lot. Which version of OneNote should I be using? Currently, there are two OneNote apps: the OneNote app on Windows which is part of Microsoft 365, and OneNote for Windows 10. All of the updates moving forward will be coming to the OneNote app on Windows. OneNote for Windows 10 will not be receiving new feature updates and will be reaching the end of support in October 2025. So just to be clear, the answer is OneNote from Microsoft 365 is the OneNote app you should be using. This app can be found in the Microsoft Store. Simply head to the store, type in OneNote in the search field and you can easily get it. Another option is to go to the OneNote Download site here and download it directly to your device.
