Fix Acrobat Window Not Staying Maximized on Windows 10
Question details
The user needs the application to remember its maximized window state upon reopening.
- Product
- Adobe Acrobat Pro DC
- Device & OS
- Windows 10
- Scenario
- Relaunching the PDF application after previously closing it while the window was maximized.
- Observed behavior
- The application fails to retain the maximized window size and opens in a restored down or different size instead.
Before modifying application preferences, ensure you have saved all active PDF documents and completely closed any background Acrobat processes using the Windows Task Manager.
Reset Acrobat Preferences to Default Settings
Clearing corrupted preference files often resolves issues with the application failing to remember the last window state.
Application preferences can sometimes become corrupted over time, preventing window states and other UI configurations from saving properly to the Windows registry.
Ensure Adobe Acrobat Pro DC is fully closed. Check the system tray to make sure no background instances are running.
Open the Windows File Explorer and navigate to the directory: C:\Users\[Your Username]\AppData\Roaming\Adobe\Acrobat\[Version].
Rename the 'Preferences' folder to 'Preferences_old'. This forces the software to generate fresh, default settings upon the next launch without permanently deleting your old data.
Restart your Windows 10 computer, open Acrobat, maximize the window, close it, and relaunch it to verify if the maximized state is now remembered.
Enable Restore Last View Settings
Adjusting the document handling preferences forces the program to remember how you last viewed your PDFs.

Frequently Asked Questions
Why does my PDF reader keep opening in a small window?
This usually happens when the application's preference files become corrupted, or when the program lacks the necessary permissions to save the last window state to the Windows Registry upon closing.
How do I force a program to always open maximized in Windows 10?
You can force any Windows program to open maximized by right-clicking its desktop shortcut, selecting 'Properties', navigating to the 'Shortcut' tab, and changing the 'Run' dropdown option from 'Normal window' to 'Maximized'.
Will resetting preferences delete my saved PDF files?
No. Resetting application preferences only clears the interface and configuration settings (like toolbars and window sizes). It will not delete, move, or modify any of your actual PDF documents.
