I think this key has to work:

Hi Shawn,

Do you have option two for resetting .mkv files? Thanks

Hello,

MKV now added to the table in option two. Media Player is the default app.

Hey , happy new year.

I have little problems with some file types icons e.g with .txt and .inf.
Generally i use filetypesman to change them. I search for the cause of the issue.
I see 2 things and i dont know if they are OK :
1) All the versions of imageres.dll at my system not contain icons
2) The .txt hash in registry is different that it is at tenforums file (downloaded). Mine is OIdx6Ti7qLU= , tenforums is veSVYadOH6E=
Could anyone tell me if they are OK ?
Finally, could you give the .inf file for Win11 , if its different than tenforums ?
Thanks.

Usually, they're the same as the default app.

You can search for the DefaultIcon subkey for file extensions listed in HKEY_CLASSES_ROOT to see the icon path.

I cant understand that.

1) The path shows imageres.dll , but its empty. Where is the specified imageres.dll ?
2) The icon that i configure is different and its correct (C:\Users\t******\Pictures\Εικονίδια\Info.ico)
and it showed correct also
3) The path at registry for C:\Users\t******\Pictures\Εικονίδια\Info.ico is that.
But when the icon of .inf files autochanged , its the same there. When i reloaded with filetypesman then it shows the correct (Info.ico)

The icon used for a file type is based on its default app, but it can be changed like below.

The imageres.dll file path is in your screenshot as %SystemRoot%\System32\imageres.dll which is C:\Windows\System32\imageres.dll

The tutorial below will show you how to extract and save the ICO file if that's what you wanted.

So , my first problem was the Resousce Hacker app. It not shows icons of imagere.dll.
I try it with Green fish editor pro and the icons appeared!
Btw while i had problems with "filetypesman" app i found at internet the "types" app. It look work OK for know.
Also as i check at registry it works with different way than filetypesman (it creates a key "types" with all user's changes inside).
Another problem is that when you take an update of windows e.g 23H2 , most or all icons goes to default.

So i asked for the path at registry to find a way to backup all file types icons by exporting the keys in one file.

Anyway we know some new things :
1) Imageres.dll at C:\Windows\System32\imageres.dll must contain icons.
2) "Resource hackers" app didnt show the icons of imageres.dll.
3) "Types" app work with other way than "filetypesman".

So for know its solved.

Thanks !!!!!!! :thumbsup:

Hello Shawn,

ANI and CUR added to option two. I hope they help.

CmdrKeene · Feb 15, 2024

No longer in my HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\ path in registry but even after restarting the cur and ani files are still associated with and showing icons for IrfanView. Must be in local machine hive?

Could be. You can try next the ANI and CUR downloads in option two below that are more thorough.

Hi, could I please get the reg files to restore defaults for the new archive file formats (.7z .bz2 .gz .rar .tar .tbz2 .tgz .txz .tzst .xz .zst) supported by win 11? Thanks!

Hello, and welcome. Done. :shawn:

magzyy · Mar 29, 2024

Hi, thanks for the welcome!
All of these worked great expect for .rar & .7z. The reg file did reset the file association, however, when looking at the 'choose defaults by file type' menu in settings, .rar & .7z have no file association and when I click to set a default app, Explorer isn't present in the list of options. Any ideas on how I can solve this issue? Explorer should definitely be on that list as I'm on build 22631.3296 and of course, the other file associations (such as .tar.gz) are working fine with explorer.
