Windows 10: Non-square images no longer show thumbnails in Small Icons or Details

Perry Mason in the case of the missing small thumbnail icons... Non-square images no longer show thumbnails in Small Icons or Details. Although it might appear to you my text here is a copy of the below link to a post at "answers".Microsoft.com by David H, I can assure you it is not but I have the identical problem and I was surprised to find someone else had to deal with the same thing https://answers.microsoft.com/en-us/...5-bb8625deacc5 Unfortunately, in Microsoft's despotic "help" culture, the threat is locked after one post by a "NicknamSam' who commented to the poster that he has the same issue and I cannot contact the author, perhaps because it points out to a newly created bug in Windows, courtesy endless updates. In previous versions I was able to see small thumbnails of image files either in the view by "small icon", "details" or "list" view mode. Now only selective files have a thumbnail icon (See screenshots below) What puzzles me was that some thumbnail icons would show but most of the others not. Until I stumbled across the aforementioned post by David H. I then realize that indeed it has to do if the actual image is rectangular or square. Checking I realized that the ones that show are indeed only from square images. About a year ago this all still worked jpg, png, bmp, pdf, etc., until Microsoft quite apparently in the need of yet another update contributed once again dozens of new bugs. Has anyone come across this issue and perhaps found where that bug is buried? Medium icon view: (all okay) Small icon view: Details view: List view:

Non-square images no longer show thumbnails in Small Icons or Details view in File Explorer

In some previous build (earlier builds of 1809 worked) I was able to see thumbnails for JPGs and PNGs at even the smallest icon sizes in File Explorer. Since I updated to the latest 1809, and then subsequently 1903, only perfectly square images show thumbnails. Non-square images now just show a blank white page icon.

Is there any way to fix this?

Test images are 192 x 128px and 128 x 128px. "Large icons" view mode:





"Details" view mode:





As you can see, in Details view mode only the square images have thumbnails. This is a massive pain since I often work in Details view but still need to be able to figure out which image is which without having to open or even just click on every one.

Icons once they are pinned show small versions and a square


I have an issue with Windows 10. When I first installed Windows 10 everything was fine but I have found that the icons pinned to the taskbar are the correct icon but they are very small and inside a square. In my case its a blue square. Any way to get those icons back to the way I had them? I already deleted the iconcache.db file and rebooted. It did not work. Any other suggestions. The icons work fine and I can live with it but it would be nice to have the larger ones back.
