- Windows
- Scenario
- Launching and using Adobe Acrobat after a recent software update.
- Observed behavior

Before proceeding, save all your ongoing work and ensure you have administrative access to your Windows computer, as you will need to repair software installations and possibly create a new user profile.
Update and Repair the Adobe Acrobat Installation
Checking for pending patches and running the built-in repair tool can fix corrupted application files or memory leaks causing high system resource usage.
Software updates often contain essential performance fixes. If an update was partially installed or files were corrupted, Acrobat might consume unusually high CPU and RAM, slowing down Windows.
Open the application and go to Help > About Adobe Acrobat/Reader DC to verify whether you are using the free Reader or a paid subscription, and note the current version.
Click on Help > Check for Updates. If any updates are available, allow them to download and install completely.
Navigate to Help > Repair Installation. Wait for the built-in troubleshooter to scan and fix missing or damaged application files.
Once the repair process finishes, restart your Windows machine to fully apply the system and registry changes.
Test Acrobat in a New Administrator Profile
Creating a new user profile helps determine if the slowdown is caused by system-wide software issues or a corrupted local user profile.

Frequently Asked Questions
Why does Adobe Acrobat use so much of my CPU and RAM?
High resource usage is often caused by automated background processes, corrupted application files, or outdated software versions. Disabling unnecessary background features or running the 'Repair Installation' tool usually resolves this abnormal resource consumption.
Can I stop Adobe Creative Cloud from launching at startup to improve Windows performance?
Yes. Stopping Creative Cloud from launching at startup prevents heavy background syncing and automatic update checks. You can disable it by opening the Task Manager (Ctrl + Shift + Esc), navigating to the Startup tab, right-clicking Adobe Creative Cloud, and selecting 'Disable'.
Does disabling 'Protected View' in Acrobat help with system speed?
It can. Protected View adds an extra security sandbox that isolates files, which may significantly slow down file loading times on some PCs. If you completely trust the source of your PDF files, you can disable it by going to Edit > Preferences > Security (Enhanced) and turning off Protected View.
