Windows 10: How to make white PNG thumbnails visible.

I have a large set of icons that have a slightly transparent circle background and a white icon in the middle of that circle. When I view them as thumbnails it's really impossible to see the icons. Even with the side preview pane it's just white. Is there a way to change the thumbnails so I can actually see them?I've attached an example of how the thumbnail view looks as well as an example of how the icon looks.

Thumbnails not visible for JPG files in Windows 10

My Computer came with Windows 10 installed. Previously I have always been able to view images as Thumbnails in the folder using the large or extra large icons in my Livedrive breifcase system where I back up all my work.

I have been through the comments and unchecked the "Always show icons not thumbnails" box and I have deleted my cache as suggested by some parties. Still no Thumbnails visible although they are visible in my Dropbox account.

Any suggestions?

 

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

 

Thumbnails not visible for JPG files in Windows 10

I refer you to the question -

I have been through the comments and unchecked the "Always show icons not thumbnails" box and I have deleted my cache as suggested by some parties. Still no Thumbnails visible although they are visible in my Dropbox account when viewed.

The "Livedrive" system uses uncryption for the "Breifcase" files - this did not affect Windows 7 which I had on an older computer and I could see jpgs etc as thumbnails.
