Windows 10: Problem to reproduce MP4 files on Windows 11

Problem on Windows 11 and/or Microsoft Teams I use Microsoft Teams at work and my team keep videos of working meetings in one specific folder in Teams. After I installed Windows 11, I can't reproduce the audio of these videos anymore. The videos even don"t start on Teams, but when I download them to my environment running Windows 11 now, the videos run but with no audio. If I move the video MP4 file to another computer runinig Windows 10, the video and audio are good, which shows the problem is on Windows 11. All drivers are updated and I participate on Teams conferences all right ima

USB doesn't display MP4 file!

I have a 300kb mix of .png, .jpg, .pdf files on a 4Gb USB drive. I added a 2Gb MP4 movie but it doesn't display in the drive files. I used CCleaner to check the drive F files .. it only shows up as 2Gb of OTHER FILES, but not in the listed files.

Any (constructive) suggestions welcome. I can't remove it as it doesn't show in the file list.

 

Playing MP4 files

MP4 is a container file, a lot depends on the codecs within that.
MP4 can be played with Windows 10 with Films & TV, Photos, Windows Media Player, and VLC.
If those can't then there must be something odd/unusual in the file.

Right click the File > Properties > Details Tab.
see if that gives you more info, should be some info on the video/audio but not codecs.

Try the suggestions from post #3.

You have to be careful as viruses are propogated by people simply changing the filename extension and auto-forwarding via an infected PC and a compromised address list.
So a targeted scan with AV is necessary for every file attachement even if apparently from someone you know.
