Can't Change Default Apps Windows 11 (OS Build 22000.120)

Hi NevGi,

I have the same problems of you: jpg mp4 mkv don't appear on file type !!!!

Your description is perfect, but anyone give you reponse on how to solve the missing file types.

Have you solved this very strange problem?

Hi, I also have the same problem, many file types (.mkv, .avi) do not exist and are not found. I simply updated Windows 10. The command posted above also gave an error and did not solve the problem. How can I do?

Same problem like a Morphy81. Have problem with .mkv files.

Thx Morphy81 that lil app help me :)

If, with File Types Manager, I change to IrfanView as default program, I receive "access denied"

.

..

What can I do?

Many thanks

Same issue here.
Can't set the default apps in Windows 11 for most photos and videos....
Totally legitimate install....

What should I do?
Also tried filetypeman, but no luck.. access denied...

I have the same problem, can't search for .jpg, .mp4, .mkv, the box is greyed out for those file types

I got it!

There are three commands you have to run from PowerShell: (I only tried in admin mode)

Get-AppxPackage Microsoft.Windows.Photos -AllUsers | Reset-AppxPackage

Get-AppxPackage Microsoft.ZuneVideo -AllUsers | Reset-AppxPackage

Get-AppxPackage Microsoft.ZuneMusic -AllUsers | Reset-AppxPackage

First one (suggested earlier, thus the solution now :) ) only works for pictures.
The second command works for videos, and the third command works for audio files.
In case there are other issues... you have to check what default app Windows uses for that. Somehow find out the packagename for it, and replace it in the command (this is how I managed to make this work.)

No restart needed, after these commands, you can set the default apps for images, videos, and music files.

-Right click on file, Open With (other app), and select: always use this. OR:

-Right click on file, Properties, and modify there. OR:

-Settings menu, Default Apps, select the app. OR:

-Settings menu, Default Apps, enter the extension (like .mkv)

(remember, these only worked for me after entering the commands above)

Hopefully I could help all, who are in need :)

Thank you this is really helpful - now you can set default apps for the most common audio and image files, but formats like MP4, OGV, AVI are still not supported (though "Movies & TV" player will open and play them when you click the files open) - in "Default Apps". when you put in ".mp4". ".avi" or ".ogv" in "Set a default for a file type or link type", "+ Choose a default" remains greyed out and you cannot choose a default app to associate the file type.
