Windows 10: Some *downloaded* videos from Youtube don't show thumbnails.

Windows 10 Pro 64-bit 20H2 19042.804

Hello!

I'd just like to start off by mentioning that I'm pretty good with PCs. I've been using computers since 1983 and I worked in IT for 20 years. So I kind of know what I'm doing. Sometimes. Some of the newer stuff confuses me, though. Get off my lawn, etc...

This is a pretty weird problem and it only started happening a few months ago. So I use video downloaders (Internet Download Manager and 4K Video Downloader mostly) to download videos from Youtube and other sites. I do this so I can keep my own copy of the video, and sometimes extract audio from them. These files are almost always MP4 or MKV.

Always in the past the thumbnails for these videos would display in Windows Explorer. Most video files show thumbnails by default, but for the ones that don't (mkv) I use the Media Preview Configurator to make them work. I've been doing that for years now with no issue.

But recently, some of the videos I download from Youtube (mp4 or mkv) don't display thumbnails in Windows Explorer. Just some of them. And Windows Explorer sort of hangs when browsing a folder in which these videos reside, sometimes to the point that I either have to restart Explorer or reboot. Once even my efforts to fix this screwed up ALL thumbnails and it took some doing to get it all working again.

I've tried converting these files to other formats using various converting tools (ffmpeg and Movavi mostly), but the converted files don't display thumbnails either. The format doesn't matter: avi, wmv, mov, mpg, m4v, etc.

It's one of the weirdest things I've ever seen.

Anyone know how to fix this? Or can tell me why this is happening?

Thanks.

File Explorer - Some PDF's show thumbnail image, some don’t

In Windows 10 File Explorer, I see thumbnails for a few of my pdf files but still see the generic Adobe pdf icon for most of them.

• In Windows 10 folder options, the checkbox for “Always show icons, never thumbnails” is unchecked.
• On the Adobe Reader preferences general tab, “Enable PDF thumbnails previews in Windows Explorer” is checked.
• Adobe Acrobat is set as my default PDF viewer.
• I have used Disk Cleanup to delete all my thumbnails to clear and rebuild the cache, yet the problem persists.

Any suggestions on how I can see all the pdf icons as thumbnails?
Windows 10 Pro, Version 1903, Build 18362.657
Adobe Acrobat Reader DC (20.006.20034)

I asked over in the Adobe Acrobat Reader forum a few days ago but have received no replies.
