Frequently Asked Questions
Why does my pen lag only in OneNote for Windows 10 and not in OneNote Online?
OneNote for Windows 10 relies on local system resources and Windows inking drivers. If there is a corrupted local file, a pending app update, or a conflicting background application running on your computer, it will only affect the desktop app, whereas the web-based OneNote Online runs within your browser environment.
Can outdated graphics drivers cause delayed handwriting?
Yes, outdated or corrupted graphics and pen drivers can cause lag when rendering digital ink. It is recommended to check Windows Update or your device manufacturer's website (such as HP) for the latest pen and display drivers.
Is OneNote for Windows 10 still being supported?
Microsoft is gradually migrating users from OneNote for Windows 10 to the unified OneNote desktop app (formerly OneNote 2016). If the Windows 10 specific app continues to have performance issues, downloading the standard OneNote desktop application from the Microsoft Store may resolve the lag.
