Windows 10: PNG thumbnails are white

In file explorer, icons for JPG files are pics, but PNG files are white thumbnails. I cleared icon cache, and followed all troubleshooting suggestions, but nothing has worked. Win10, all updates, SSD and HDD have plenty of room., no other problems

PDF thumbnails inside of a white square

Hello

Suddenly, my pdf thumbnails appear inside of a kinda white square, like this:





I have no idea why this started happening, but installing an older Adobe Reader version has not helped and I cannot undo the most recent Windows update anymore.

I've tried these, but neither helped:

- Clear Thumbnail Cache
- Delete IconCache.db
- Use this Fix
- In Adobe Reader, turn off and on miniature preview
Between these steps, I of couse always restarted the computer

I want it to look like this:





(for some reason, I have this problem only on my laptop, but not on my desktop pc, even if both are the same Win 10 version, same updates, same Reader version, etc)

Does anyone have an idea how to get rid of that?

Thanks

 

File Explorer not showing thumbnails

Brink,

Many thanks for you reply. I have done all the steps you suggested, but no change,

When I open a folder containing photos, some open correctly but the vast majority open with thumbnails, but they very quickly get overwritten and you can not longer see the thumbnails.

Are there any more suggestions?

 

Windows 10 tiles are blank / white with no thumbnail icons!

Hi All

Running Windows 10 operating system... I have the same issue but on my desktop and Taskbar at the bottom of the screen... White Box Icon... If I click the start it shows the correct icon but if I open it from there it shows white on the task bar...

Tried this:

Method 1: You may also try to enable or disable the thumbnail preview using group policy editor.

Follow the steps to do so:

• Press Windows and R key together to open the run box.
• Type “gpedit.msc” in the box and hit Enter.
• Now, navigate to User Configuration, Administrative Templates, and Start Menu and Taskbar in left pan of Group Policy Editor.
• Locate “Turn off Taskbar Thumbnails” in right pane of Group policy editor and double click on it.
• Select Disable and click on Apply and then on OK.
• Check if you are able to view the images.

But computer said no file found...
