Windows 10: Windows 11 Thumbnails not showing on some images

New laptop running Windows 11 with Dropbox and Carbonite only displays some image thumbnails. We scanned for malware, ran sfc /scannow, reset folder defaults, deleted thumbnail cache, and rebooted. There are no missing Windows updates. Opening the photo to view it and then closing it, doesn't help either. Does anyone have any other suggestions?

Thumbnails won't show images

On Windows 10 my images aren't showing the image in the thumbnail. It's showing a pieces of blank paper. This randomly started happening today. I have checked the "Organize" setting and the "Always show icons, never thumbnails" is unchecked. I'm not sure
what else to do. Any suggestions?

 

Image thumbnails not showing

Hi,

Your concern about the performance of your device when viewing photo thumbnails can be due to its configuration and/or corrupted system files. To better understand your concern, we'd like to know the following:

• The last changes made/activities performed on your device prior to your concern.
• If you've experienced your concern on multiple image file extensions. Examples are JPEG, JFIF, BAT, GIF, and PNG.
• The version and build of Windows 10 that you're using on your device. To check this, you can perform the steps posted on this
  
  link.

Based on the steps that you've already performed, we'd recommend performing the following to recreate the thumbnail cache:

• Open File Explorer.
• On the left pane, click This PC.
• Right-click the C: drive where Windows 10 is installed, and select Properties.
• Click the Disk Cleanup button.
• Check the Thumbnails option, and uncheck all the other options.
• Click OK.
• Click Delete Files to confirm and to complete the task.

In the event that the steps did not suffice, we'd recommend going through the commands posted below to further isolate your concern:

• Open Start.
• Search for Command Prompt.
• Right-click the result and select Run as administrator.
• Type the following command to stop File Explorer and press Enter.
  
  taskkill /f /im explorer.exe
• Type the following command to delete all the thumbnail database files without asking for confirmation and press Enter.:
  
  del /f /s /q /a %LocalAppData%\Microsoft\Windows\Explorer\thumbcache_*.db
• Type the following command to start File Explorer and press Enter.
  
  start explorer.exe
• Close Command Prompt to complete the task.

Note: We understand that you've already performed two of the commands listed. We've detailed the known succession and format of commands that works on many occasions on other users.

Also, if you've only experienced this issue on images with JPEG/JPG/JPE file extensions, we'd recommend

downloading the registry items that we've prepared for you and merge them on your existing registry configuration. To do this, you can perform the following:

• Once download is complete, right-click on one of the registry items.
  
  
  
  
• Select Merge.
  
  
  
  

Note: Changes in the registry may cause issues on your device when done incorrectly. To secure your device, we'd recommend backing it up by performing the steps posted on this

link. The article also includes steps on how you can restore them in case you need to.

We look forward to your response.

 

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.
