Question details
The user is experiencing significant delays when opening PDF documents locally using Adobe Acrobat Pro DC, whereas the same application loads files quickly during a remote desktop session.
- Product
- Adobe Acrobat Pro DC
- Device & OS
- Windows 10
- Scenario
- Opening local PDF files on a physical Windows 10 desktop environment.
- Observed behavior
- PDF documents take an unusually long time to open locally but render almost instantly when accessed through a remote session.
Ensure your Windows 10 operating system is fully up to date and close any heavy background applications that might be consuming system resources or conflicting with local rendering.
Update Adobe Acrobat and Restart Windows
Installing the latest software patches often resolves performance bugs affecting local file loading speeds.
Software bugs specific to local graphics rendering or background processes can cause performance drops. Updating Adobe Acrobat ensures you have the latest performance patches.
Open Adobe Acrobat Pro DC, click on 'Help' in the top menu bar, and select 'About Acrobat' to verify your currently installed version.
Click on 'Help' again and select 'Check for Updates'. Wait for the application to scan for available patches.
If an update is found (such as version 21.05.20060), follow the on-screen prompts to install it, then completely restart your Windows 10 computer to apply the changes.
Reset Acrobat Preference Settings
Corrupted preference files can cause Acrobat to run slowly. Resetting them to default can restore normal software performance.
Create a New Windows Administrator Profile
This helps determine if the slow loading issue is tied to corruption within your current Windows user profile or a system-wide problem.
Open PDFs Quickly with WPS Office

- 1. Download WPS Office: Download and install WPS Office for free from the official website.
- 2. Open your PDF file: Right-click the PDF file that was loading slowly, select 'Open with', and choose 'WPS Office'.

Frequently Asked Questions
Why does Acrobat open PDFs fast remotely but slow locally?
Remote desktop sessions often bypass local graphics rendering processes or local security software scans that might be bogging down Acrobat on your physical Windows 10 machine. Network mapping differences can also affect how Acrobat verifies file permissions.
Will resetting Acrobat preferences delete my saved PDF files?
No, resetting preferences only restores the application's internal UI and tool settings to their default state. Your actual PDF documents, bookmarks, and files remain completely safe and unaffected.
How can I manually download an Acrobat DC update?
You can download optional or specific version updates directly from the Adobe Acrobat Enterprise Toolkit (ETK) Release Notes page. Find the patch matching your system architecture and run the downloaded installer.
