File Explorer Lagging and Not Previewing PDFs

I have Windows 10, and use Edge to view my PDF Files.

When I open File Explorer it takes a second to open, however, when I have the Preview Pane option on, it almost freezes.

When I try to select a new file, it takes a while to respond and when using my keyboard arrows to go from one file to the next it lags before I can select the next one.

This is what I have already tried:

1. Ensure the Preview Pane Isn't Disables (within File Explorer)

2. Restarted Windows Explorer (Using Task Manager)

3. Made sure "Show preview handlers in preview pane" box was checked in the view Options.

4. Made sure "Always show icons, never thumbnails" box was checked in the view Options.

5. Changed the Open File Explorer to: "This PC"

6. Checked Hard Disk Response Issues using "Command Prompt" "Chkdsk"

7. Updated Graphics Driver.

nothing has helped.

I would like to avoid downloading any new programs and would like to keep Edge as the default viewer.

Not sure If this makes a difference but all my PDF files have "Microsoft Edge Document" as Type of file.

 

How to fix PDF Preview in File Explorer?

I need help to Preview PDFs with File Explorer but below steps are not working.

[Fix] PDF Thumbnail and Preview Not Showing in Explorer

Preliminary step – Enable thumbnails and preview handlers in Explorer

1. Open Folder Options
   
2. Enable “Show preview handlers in preview pane”
   
3. Uncheck “Always show icons, never thumbnails
   

If thumbnail and preview functionality is still missing for PDF file types, proceed to the next step.

Microsoft PowerToys is not acceptable alternative because it is not approved; my guess is PowerToys utility could wreak havoc within the Windows operating system; as such, novice users have often been encouraged to use caution.





Operating System: 19041.1.amd64fre.vb_release.191206-1406 10.0.0.0.2.4
