[SOLVED] [SOLVED] Windows 10 Explorer - No thumbnails and no data like 'lenght' for MP3 / MP4 / PDF

[ChroMe55555]

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), see the first attachment "FileExplorer.jpg". If I open my MP3 files with MP3Tag (a tool to add metadata to MP3's, see the second attachment "MP3Tag.jpg"), I see that the cover and the metadata is still there. So I think it is a display issue in my explorer.
In the third attachment "Desktop.jpg" you can see that for images (green rectangle), the thumbnails are still working, but for MP3/MP4 they are not shown anymore...

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
• Ran CMD as administrator > sfc /scannow

Nothing seems to work at this moment.

did you try to uninstall the updates that caused problem?

Hi,

Yes I tried to, but it didn't help...


I might found something which might be related (I don't know), but in Firefox I now get the message:

...which I never received before, so maybe something is corrupt there. I tried to uninstall and reinstall it, but I cannot find it in the Windows features list. Could this be related to my issue? And do you have any tips on how to properly uninstall and reinstall this media feature pack?

I found the feature in the Settings > Apps > Optional features > Add a feature,

but when I try to install it, it fails:

I also noticed Windows Media Player is no longer installed/available...

This extra info regarding my Windows might also help:

• the current version
• the update history

ALL IS SOLVED, steps followed:

• Ran the troubleshooter 'Windows Updates' which detected and fixed some issues
• Ran the search for Windows Updates again which now found 2 additional updates and installed them:
  • KB4580419 - 2020-11 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 version 2004 for x64
  • KB4586781 - 2020-11 Cumulative Update for Windows 10 version 2004 for x64-based systems
• Rebooted my system and all was fine again (thumbnails of MP3/MP4/... are back, MP3 artists, titles, lengths etc are back)

Thank god for Friday the 13th of the incredible year 2020
