Hello Andy H,
I’m Gunasekar and I will be happy to help you with your question, I am a Microsoft consumer like you.
I understand that you are having trouble with OneNote performance on your Windows device. You could try the following suggestions below and share the outcome.
- Check your pen's battery -
If you're using a Bluetooth-enabled pen, check the battery level to make sure it's not running low.
- Update OneNote -
Click File > Accounts > Update Options > Update now.
Restart your device.
- Ensure you have the latest version of the Operating system running on your device.
Go to settings > System > Update and security > Windows updates > Search for the latest updates and install them.
- Try disabling any unnecessary background processes that may be running on your device, as these can take up resources and slow down OneNote.
- Uninstall and re-install the latest version of OneNote and check the outcome.
