Update and Repair Acrobat Reader
Updating to the latest version or running the built-in repair tool usually resolves bugs that prevent settings from saving properly.
Software glitches often cause application preferences to reset. Adobe frequently releases patches to address these exact bugs, making an update the first logical step.
Open Acrobat Reader, navigate to Help > Check for Updates in the top menu, and install any available updates (such as version 20.006.20042 or newer).
Restart the application, select the Dark Gray theme again, and close the app to test if the setting holds.
If the issue persists, go to Help > Repair Installation (available on Windows) to fix any corrupted application files.
Perform a Clean Reinstallation
Use this method if repairing doesn't work, as a complete removal ensures no corrupted preference files remain on your system.

Frequently Asked Questions
Why does Acrobat Reader keep changing my theme back to light?
This usually happens due to outdated software, corrupted installation files, or incorrect Windows permission settings preventing the application from saving preference changes to the system registry.
Does Adobe Acrobat Reader have a true Dark Mode?
Yes, you can change the display theme to Dark Gray by going to View > Display Theme > Dark Gray. However, this primarily changes the user interface elements (like menus and toolbars) and does not automatically invert the colors of the actual document background.
Where can I find the Acrobat Cleaner Tool?
The Acrobat Cleaner Tool can be downloaded from the official Adobe Labs website. It is specifically designed to safely remove standalone Acrobat and Reader installations, including leftover preference files.
