Windows 10: PDF Thumbnails disappeared after update

Windows 10 version 2004 Japanese updated

Soft/Drivers updated


I do not know the exact reason why PDF file thumbnails disappeared. I did not install or uninstall any software.

I have enabled PDF thumbnails in the Windows explorer. I have also cleared the thumbnail cache. I have also reinstalled

the Adobe Acrobat Reader DC.


Is there any solution to view PDF thumbnails?

Please share your thoughts.

Thank you in advance.

PDF thumbnails disappeared in Windows Explorer

Hello
Edition Windows 10 Pro
Version 20H2 Installed on ‎28-‎May-‎20OS build 19042.746
Experience Windows Feature Experience Pack 120.2212.551.0
PDF APP: Nitro Pro, Sumatra, Foxit
After the Windows update of mid Jan 21 and the update to Nitro 13.33 Pro the thumbnails of PDF files that have always been visible in Windows Explorer, disappeared. The space of the miniature rests blank; only the small icon of Nitro is visible in the bottom right corner.
If i change the default PDF programs (Sumatra or Foxit) the thumbnails rest invisible, with the exception of the relevant icon. This is annoying. I did not try with Adobe: i need a PDF editor and I have Nitro PRO. The File Explorer was used however it only change the default PDF Icon from large to small (always show icons, never thumbnails).
Any suggestions? thumbnails are convenient. The root appears to be with W. Explorer, not with the PDF app.

 

File Explorer - Some PDF's show thumbnail image, some don’t

In Windows 10 File Explorer, I see thumbnails for a few of my pdf files but still see the generic Adobe pdf icon for most of them.

• In Windows 10 folder options, the checkbox for “Always show icons, never thumbnails” is unchecked.
• On the Adobe Reader preferences general tab, “Enable PDF thumbnails previews in Windows Explorer” is checked.
• Adobe Acrobat is set as my default PDF viewer.
• I have used Disk Cleanup to delete all my thumbnails to clear and rebuild the cache, yet the problem persists.

Any suggestions on how I can see all the pdf icons as thumbnails?

I asked over in the Adobe Acrobat Reader forum a few days ago but have received no replies.

Preview and thumbnails of pdf files are not available

Hi Michelle, my name is Martin and I'm an Independent Advisor. I'll try to help you here.

Preview and Thumbnails of PDF files can be disabled on your PC . . .

I suggest that you follow steps below to enable this feature

Start Adobe Reader

Tap on Edit in the menu bar and select Preferences

Under Categories highlight General

Put the checkmark next to the box Enable PDF thumbnail previews in Windows Explorer

I also recommend the article - Enable thumbnail of PDFs in Windows Explorer to get further information
