Click the 'Get updates' button at the top right. Wait for the system to scan and automatically install any pending updates for OneNote for Windows 10.

Frequently Asked Questions
Why do my smooth lines become blocky after I finish drawing in OneNote?
This typically occurs due to a glitch in OneNote's handwriting processing engine, which simplifies or redraws the vector paths of your strokes after you lift the pen. An outdated app version is usually the culprit.
Does my stylus affect the line quality in OneNote?
While hardware can cause jitter, if the line appears perfectly smooth while you are drawing and only turns blocky afterward, it is a software rendering issue, not a defect with your stylus or touch screen.
Will resetting OneNote for Windows 10 delete my notebooks?
Resetting the app removes local app data and cache, but notebooks that are successfully synced to your OneDrive will remain safe. Always verify your notes are synced online before performing a reset.
