Windows 10: Restore File Explorer Default Thumbnail size

Hello,

I am using Win10pro v1803 bld 17134.407


All my picture thumbnails in explorer are converting to square format from the very nice original aspect ratio. This may have started with my recent system updates a few days ago.


Can I put them back to the rectangular/as-taken aspect ratio?

Happy Trails


***Title modified from: All picture thumbnails are now square can I get set them back to rectangular or original aspect ratio?***

Windows Explorer crashes and thumbnails problem

Hi, I hope you can help me.
Windows Explorer is no longer showing thumbnails on files played by Windows Media Player. I've run cmd and regsvr32 shmedia.dll and regsvr32 shimgvw.dll. That seemed to solve the problem...but it created a different one. Now when I try to open a folder on an external hard drive it crashes. I read in an old 2008 post it was an avi file causing the problem and suggested the run cmd regsvr32 /u shmedia.dll. That solved the opening problem but recreated the thumbnail problem. Any help to achieve both functions would be greatly appreciated. Thank you.

 

Displaying Thumbnails for .jpg files in Windows 10 File Explorer

Thanks for your suggestion.

As "recommended for Windows 10", "Photos" is the default app for "Photo viewer" (.jpg isn't really listed as the file extension in the settings).

Do you have another app you would suggest?

By the way, my photos open and display just fine, the issue is the general absence of thumbnails in File Explorer.

 

In Windows 10, how can I enlarge thumbnail size?

Even after selecting Extra large icons, the thumbnails are too small for me to discern the images. I completed the steps for:

1. Option 1: 'To Turn On Thumbnail Previews in File Explorer'.
   
2. Changing Image Thumbnail Size per this Registry Hack Method.
   

But my thumbnails have not enlarged.
