Configure Preferences to Remember the Tools Pane State
Enable the built-in preference that forces Adobe Reader to remember whether you left the Tools pane open or closed.
Adobe Reader includes a specific setting designed to control the default behavior of the right-hand Tools pane. Ensuring this is active and properly registered by the application usually resolves the issue.
Launch Adobe Acrobat Reader DC and navigate to 'Edit' > 'Preferences' from the top menu, or press Ctrl+K on your keyboard.
In the Preferences window, select 'Documents' from the Categories list on the left-hand side.
Check the box next to 'Remember current state of Tools pane' under the Open Settings section, then click 'OK' to save.
Click the small arrow on the vertical divider to collapse the Tools pane, then close and reopen Adobe Reader to ensure the state is saved.

Toggle the Tools Pane Using Keyboard Shortcuts
Use a quick keyboard shortcut to hide the Tools pane if the software fails to remember your preferences due to a glitch.
Experience a Clean, Distraction-Free Reading Interface with WPS PDF
If Adobe Acrobat Reader DC continues to force unwanted side panels open, consider switching to WPS Office. The built-in WPS PDF reader offers a lightweight, user-friendly experience without intrusive toolbars, allowing you to focus entirely on your documents.

Frequently Asked Questions

Adobe Acrobat Reader DC is designed by default to display the Tools pane to highlight its premium features and tools. To stop this behavior, you must explicitly enable the 'Remember current state of Tools pane' option in the Documents preferences.
Will updating my Adobe Reader fix the Tools pane bug?
Yes. If your software is experiencing a persistent glitch where the 'Remember current state' option fails to work, navigating to Help > Check for Updates and installing the latest patch can often resolve unexpected UI behaviors caused by known bugs.
How do I completely hide the right-hand toolbar in Adobe Reader?
You can hide it temporarily by clicking the small collapse arrow on the vertical divider next to the pane, or by pressing Shift+F4. To keep it hidden permanently, you must combine this action with enabling the 'Remember current state of Tools pane' setting.
