Identify and Compare OneNote Versions
Checking your exact application version helps clarify if the layout change is due to using a different app edition on different devices.
Microsoft maintains different versions of the app, such as OneNote for Windows 10 and the standard OneNote desktop application. These versions have distinct interfaces.
Launch OneNote on your device and navigate to the 'File' tab in the top ribbon.
Click on 'Account' in the left-hand menu to view your exact product information, build number, and version details.
Repeat this process on your other computers or devices where the layout looks different to determine if you are running mismatched versions.

Check the Interface in OneNote for the Web
Viewing your notebooks online can help determine if the layout change is a local client issue or a universal interface rollout.
Update to the Latest Release
Microsoft rolls out interface updates gradually. Ensuring your app is fully updated guarantees you have the most consistent experience available across all devices.

Frequently Asked Questions
Why does OneNote look entirely different on my home PC compared to my work computer?
Microsoft frequently rolls out new interface updates gradually to different user groups. Additionally, you might be running different applications, such as the pre-installed OneNote for Windows 10 versus the standard Microsoft 365 OneNote desktop app.
Can I revert the new layout to the old side panel style?
Generally, once an interface update is fully rolled out by Microsoft, it cannot be reverted. However, you can explore the 'View' tab in the ribbon to customize how tabs and navigation panes are currently displayed.
Are there functional changes alongside these new tab indicators?
The changes to the side panel colors and tab indicators are primarily cosmetic updates intended to modernize the interface. Your synced notes, structure, and core functionalities remain entirely unaffected.
