Windows 10: [Setting] Choose defal apps by file type Suggestion

Hello,


When I change a default apps by file type: .txt from Notepad to VSCode. I must be scroll until I find the .txt.

And with the many hundreds of file type. It takes time to scroll until find .txt. After all, I can change the default app.

If we have an search box for this screen. It is very good for that.

I use windows 10 version 1809.


Regards,

.iso extension missing from settings/choose default apps by file type


This ties partly into my other issue of not being able to mount ISO files in windows explorer. I am getting no luck on fixing that separate issue, so maybe if i tackle it at a different angle, the other problem could be solved as well. Please do not move this issue to Virtualization.



The Issue

Basically, in my "Choose default apps by file type" settings window, the .iso extension is missing. I am running Windows 10 Home Version 1809



In the past, it was there, and also in the past, I was able to mount .iso files by right clicking, and selecting "mount". The option to mount is still there;





But gives me this error;





(this is part of my secondary issue being taken care of in another thread (hopefully)) so please don't move this thread to virtualization.

What I want:

I want the .iso extension back in my list of extensions in my settings --> default apps--> choose default apps by file type window.


Things I have tried;

• 1) Going to Settings - Indexing Options
  2) Advanced button
  3) File Types tab
  4) Add New Extension to List box, type in extension, (without a period) in this case "iso"
  5) Click OK and Close
• Right clicking any .iso file, and selecting "open with", then selecting "choose another app", and then selecting "Windows Explorer".
• Right clicking any .iso file, selecting "Properties", then selecting the "Change" button under "opens with" and selecting "Windows Explorer".
• Restoring the default Windows file extension through registry fix detailed here with OPTION TWO and selecting the .iso reg file, adding it to my registry, and restarting my pc.
• I created a "fake" extension named .isotest. It successfully appeared in the settings menu(see picture above)
• Ran "DISM /Online /Cleanup-Image /RestoreHealth" in elevated cmd prompt and then "sfc /scannow" in an elevated command prompt. No issues were found.

In the registry, it shows that iso files are opened with Windows.IsoFile. Looking under the reg key, I cannot tell if anything is incorrect. Below are the reg keys associated with Windows.IsoFile and the .iso key in Computer\HKEY_CLASSES_ROOT\















I'm not sure what else to do aside from formatting my pc which I really don't want to do for this issue. Help is greatly appreciated. Please read the whole post before suggesting things please.

Thanks.

 

.iso extension missing from settings/choose default apps by file type

By default iso doesn't exist. Inspecting the reg file from the tutorial confirms this. Installing a program that specifically handles iso files such as Imgburn, Poweriso, will create the necessary registry entries and .iso will be listed in Settings.
