Perform a Repair Installation in Adobe Acrobat
Using the built-in repair tool is the most effective way to fix corrupted application files and resolve recurring performance degradation.
Over time, application files or background cache configurations can become corrupted, leading to significant drops in performance. Running the repair installation built into Acrobat re-evaluates these core files and replaces any damaged components without requiring a full manual reinstallation.
Launch the Adobe Acrobat application on your computer.
Navigate to the top menu bar and click on the 'Help' tab to open the dropdown menu.
Select 'Repair Installation' from the list of options. Follow the on-screen prompts to allow the software to scan and fix corrupted files.
Once the repair process is fully completed, close Adobe Acrobat completely and reopen it. Test the application by opening and closing several PDFs to verify the speed.

Frequently Asked Questions
Why does Adobe Acrobat get slower the longer I keep it open?
This is commonly caused by memory leaks, an accumulating list of recent files, or cached data that continuously builds up in the background. As the cache grows, it forces your computer to consume more RAM, leading to sluggish performance.
Will reimaging my computer permanently fix PDF unresponsiveness?
Not necessarily. If the installation package you use after reimaging contains the same software bug, or if your network profile settings sync corrupted preferences back to the new system, the slow performance will persist.
How can I reduce the background memory usage of my PDF reader?
You can try disabling certain security features like 'Enable Protected Mode at startup', turning off automatic synchronization features, and clearing your recent files list under the application preferences.
What should I do if the Repair Installation fails to fix the lag?
If the built-in repair tool does not resolve the issue, you may need to perform a clean installation. This involves completely uninstalling the software using a dedicated cleaner tool, restarting your PC, and downloading a fresh installation package from the official website.
