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

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 meafterentering the commands above)

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

Thanks, this seemed to work perfectly for most.

Yet, even after doing these commands in PowerShell:
the file extension ".TIF" is missing.

I cannot assign any app to a file format, that I cant find.

Can I add it manually?

Yes, really. And latin is the most spoken language on earth.

Microsoft made it impossible to change standard appss for common file extensions.

Windows 10: change image viewer: 1 click.

Windows 11: click what you want, it's blocked. greetings from evil microsoft, harrharr.

yes, really easy to change png and jpg. you simply can'T do it without a registry hack.

Run in Powershell with admin privileges, not a CMD

Thank you, it works! I was ready to revert to win 10.

Thank you. This solved my problem <3
