Windows 10 – Some show thumbnail image, some don’t

[strider8]

In Windows 10 File Explorer on the icon views, I would like to see the first page display for pdf files rather than the generic pdf icon. In Windows 10 folder options I have the checkbox for “Always show icons, never thumbnails” unchecked. On the Adobe Reader preferences general tab, I have “Enable PDF thumbnails previews in Windows Explorer” checked. With those settings, I see thumbnails for a few of my pdf files but still see the general Adobe pdf icon for most of them.

I have used Disk Cleanup to delete all my thumbnails to clear and rebuild the cache, but the problem persists. Do you have any idea why I’m still seeing icons instead of thumbnails for most of my pdf files?

I have the same problem.  Spent time on Adobe support chat to no avail.  Searching endlessly to solve.

I couldn't find a solution with Adobe. At the suggestion of others I tried Foxit PDF Reader which worked great and shows the 1st page icon if that's what you want. If you're just using Adobe Reader, give Foxit a try. It's free and now that I'm used to it, I like it better.
