PDF Thumbnail Preview in Windows Explorer without installed PDF Preview Handler?

Can PDF thumbnails in Windows Explorer (7 or 8 or 10) show the first page of the PDF file without having to install a custom PDF Preview Handler from Adobe or Foxit or from Tracker Software or from one of the other known preview providers?

Please note: I do NOT mean the specific File Preview pane in Windows Explorer where one can scroll through all the pages of a PDF document (which is provided by a PDF Preview Handler e.g. from Adobe)!

I explicitly mean the thumbnails inside the Windows Explorer browsing area when the Windows Explorer View Mode is set to THUMBNAILS.

If the answer is NO: Can you suggest a MINIMAL installation package for this functionality (thumbnails displaying PDF first page) without having to install Adobe Reader or one of those large PDF packages from one of the other PDF brands?

 

PDF Previews Not Showing In Windows 10 File Explorer

I wanted my Window 10 File Explorer to display .pdf file previews like my Windows 7 so I started researching and came up with several different solutions, none of which worked for me.



Prime among the solutions was Option 1:



1. Open file explorer

2. Click view on the top of the file explorer.

3. Select preview pane option and see if it helps.



And Option 2:

• Open the reader,
• Go to Edit
• Then Preferences
• Go to General Tab
• And check "enable PDF thumbnail previews"

Even after using Option 2, it still didn’t work but then after going to Help > Repair Installation in Acrobat Reader DC it works just fine.

In the Preferences dialog box, choose General in the Categories list, and then select the Enable PDF thumbnail previews in Windows Explorer check box.

Click OK.

Wait for a few seconds while Acrobat is configured to show thumbnail previews in Windows Explorer.

Restart then check again.
