Thumbnails in File Explorer Windows 10
Hi, thanks in advance for any help you can give regarding this sudden change in viewing PDF thumbnails in File Explorer. Prior to a couple of days ago, I was able to view PDF thumbnails scrolling through File Explorer. I made no changes to any other settings or updates, but now when I try to view them, this is what I see:

I un-installed and re-installed Adobe Reader, checked the Adobe Reader Enable Preview Option, but nothing has corrected the issue.
Any suggestions?
Kathryn
