How to Stop the Comments Pane from Opening Automatically in Adobe Acrobat
Question details
The user wants to stop the comments pane from expanding automatically whenever a PDF file containing comments is opened.

- Product
- Adobe Acrobat
- Device & OS
- Windows
- Scenario
- Opening and viewing a PDF document that contains annotations or comments.
- Observed behavior
- The comments pane automatically opens upon loading the document, which disrupts the default reading experience.
Before modifying your application preferences, ensure you save any currently open PDF documents and check that you have a stable internet connection if you need to download updates.
Disable the Comments Pane Setting in Preferences
The most direct way to fix this issue is by unchecking the specific commenting preference within Adobe Acrobat.
Adobe Acrobat includes a default preference that triggers the comments pane to open automatically so users don't miss feedback. Disabling this setting will restore a clean viewing experience.
Navigate to Menu > Help > Check for Updates to ensure your application is running the latest version, as bugs in older versions might prevent settings from saving properly.
Go to Menu > Preferences, or simply press the Ctrl+K keyboard shortcut to open the preferences window.
In the left-hand Categories sidebar, select 'Commenting'.
Find and clear the checkbox labeled 'Show comments pane when a PDF with comments is opened', then click OK to save your changes.
Clean Reinstall Adobe Acrobat
If the preference change does not remain disabled after saving, your application installation might be corrupted and requires a clean reinstall.
