I would love to see Blender file thumbnails in Windows 10/11 Explorer, but the fix of running blender -R at the Command window never makes a difference.
I have opened a Command window as an Administrator and successfully changed the directory to the current version of Blender and run the command Blender - R.
I have tried running it multiple times then rebooted my PC and also cleared the thumbnail cache, but I never see thumbnails, only the large blender icon for my files. Yes, I do see a success message each time.
Are there are other tricks or third party tools to display Bender files as thumbnails? (Most of my files are simple models for 3D printing),
