Windows 10: No thumbnails and data like 'lenght' for MP3 / MP4 / PDF

Hi,

This morning I had a popup that Microsoft needed to install some updates, I agreed and rebooted my system, but now I don't have any thumbnails anymore for MP3 / MP4 / PDF files.

I'll focus on the MP3 extension here, normally the file itself has the cover art shown as a thumbnail and now all MP3's look the same, they all have the icon of the program which I open them with.
Another thing I notice is if I go to a directory with MP3's, all columns such as artists/title/length etc are empty (they used to contain data). If I open my MP3 files with MP3Tag (a tool to add metadata to MP3's), I see that the cover and the metadata is still there. So I think it is a display issue in my explorer.

I run Windows 10 64 bit

I already tried:
- File Explorer > View > Options > View > Always show icons, never thumbnails = UNCHECKED (+ restart computer)
- Windows Performance Options > Show thumbnails instead of icons = CHECKED + Save taskbar thumbnail previews = CHECKED (+ restart computer)
- C:\ drive > Properties > Disk Cleanup > Thumbnails CHECKED (+ restart computer)
- Ran the bat file from the tutorial Clear and Reset Thumbnail Cache in Windows 10

Nothing seems to work at this moment.

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

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

Preview and thumbnails of pdf files are not available

Hi Michelle, my name is Martin and I'm an Independent Advisor. I'll try to help you here.

Preview and Thumbnails of PDF files can be disabled on your PC . . .

I suggest that you follow steps below to enable this feature

Start Adobe Reader

Tap on Edit in the menu bar and select Preferences

Under Categories highlight General

Put the checkmark next to the box Enable PDF thumbnail previews in Windows Explorer

I also recommend the article - Enable thumbnail of PDFs in Windows Explorer to get further information

.mp4 thumbnail icons!?

Did the feature update this morning and now I don't get thumbnail previews for .mp4 files only!

Any idea why anyone!? I like my thumbnails!!!

Chuter.

EDIT: To be more specific it seems it's only not going to show me the .mp4 video thumbnails for the videos that came from my MotoZ2 play device which are in 4k. if that may have anything to do with it?
