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

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.

I can agree, but may I remind you, that I'm not a MS employee, just some random guy on the internet, who also had the issue :D
(and is now thinking very hard about buying a new macbook pro :D )

This could have been Microsoft's chance to redeem all the ugly Windows systems (8, 8.1, 10).
And it really does look good!!!

And what do the do? F*** it up with TPM 2.0 requirement and billions of software bugs.
-My "widgets" panel is in arabic. (i am not arabic, I don't understand it)
-Default apps management is too clumsy. Even when it does work the intended way.
-Multimonitor handling should be the "new big thing". yet, all the windows are messed up when returning from sleep.
-Task bar icons disappear every time I alt+tab from a fullscreen game, and they take about 5-8 seconds te reappear. (like restartint explorer.exe)
-all these abovementiones issues were well known in the beta version. This topic is also not new.
-And I really-really have to mention TPM 2.0 requirements again... very few people will buy a new system for this.
Some(like me) may use a hacked installer. But for others.... very-very-very stupid decision!!!!
They only should have limited company security-related stuff to this...
Or the "Pro" version worst case scenario(not the home)
Still stupid... They kick themselves in the balls with this.
Computers will get old eventually. People will buy new ones eventually. TPM will be default eventually. Why force?

So I have a hard time liking Windows 11, even though I kinda like it...

You may be right. I've installed W11 to a few friend lately, and I think also GOM Player may break this too (or VLC... not sure)

Things sometimes change in the operating system from time to time, which is fine. Some things work differently.
And yes, these apps may have used a method doing something, that was not... the intended way, yet worked.
(did some registry stuff on the own accord and it worked so far)

But.... I still think, that this functionality should not break this easily. Especially as multiple apps may do this.

So this is nice example of something not being Microsoft's fault... yet they'll gt the blame, and they will need to come up with an idea to fix this eventually.
(or people will update ther installers eventually, and this topic will be pretty popular up to that point :D )

The software engineer's life is never easy :D

I'll take a few seconds, and try to notify the creator or Irfanview about this :)

Have a nice day, and thank you for the insight!

The script you used was too aggressive.

Reinstall the Photos, Groove, and Movies if you have removed them; Then:

from @takysoft on elevenforums.com

For some reason Windows 11 has some preconfigured apps "buggy", and you need to reset them. (in my case picture viewer, video and music player)

Open a Powershell(preferably in admin, I only tried in admin), and enter these command:

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

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

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

You should now be able to choose default apps in the normal manner.

Once you are set up properly you can use:

Get-AppxPackage *Microsoft.Windows.Photos* -AllUsers | Remove-AppxPackage

Get-AppxPackage *Microsoft.ZuneVideo* -AllUsers | Remove-AppxPackage

Get-AppxPackage *Microsoft.ZuneMusic* -AllUsers | Remove-AppxPackage

To remove them safely.

Well the debloat script I used was from Chris Titus Tech. I having using this debloat script since a year ago no problems occured not once.

Well I made my own Windows 11 ISO from UUP Dump website. And I thought of reinstalling Windows 11 for 2nd time but before that i uninstalled the Windows 11 Cumulative Update (KB5005188). Which reverts the setting layout and explorer layout but because settings reverted back to how it was on windows 10 I was able to change all the default apps.
