Default File Associations - Restore in Windows 8

How to Restore Default File Extension Type Associations in Windows 8 and 8.1

information   Information
This tutorial will allow you to restore the default registry entries and program associations for the file extension type and protocol of your choice in Windows 8, Windows RT, Windows 8.1, and Windows RT 8.1.

This can be helpful for example when a file extension type opens with the wrong program by default, has the wrong icon, or is missing or corrupted in the registry. Downloading the .reg file for the selected file extension below, will restore that file extension back to default for all of these items above.

Default program associations for file extensions are a per user setting by default, so you will need to be logged on to the effected user account to be able to restore the default associations of the file extension for that specific user account.

warning   Warning
These default file associations should only be used in Windows 8 and 8.1.

Note   Note
The list of available default file extension and protocol associations below is just a start for now, and is a work in progress.

I'll constantly be adding more to the list, but if one you need is not listed yet below, then please post a request for it. I'll be happy to get it added to the list.




Here's How:

1. Click/tap on the link of the file extension type or protocol in the table below that you would like to restore the default associations of to download it's .reg file.

2. Save the .reg file to your desktop.

3. Double click/tap on the downloaded .reg file to Merge it.

4. If prompted, click/tap on Run, Yes (UAC), Yes, and OK to approve the merge.

Tip   Tip

  • If you are signed in as a standard user account, then you will also get a Cannot import type error. Just click/tap OK for it. This is normal since what cannot be imported can only be done so by an administrator account instead. It will still restore the default associations of the file extension if the standard user used Open with to select the wrong program to open the file with.

  • If the .reg file is not able to Merge, then double check in Default Programs to make sure that the .reg file extension has it's Current Default program set as Registry Editor (C:\Windows\regedit.exe). Afterwards, try merging the .reg file again.



5. Sign out and in, or restart the computer to apply.

6. If you are logged in as a standard user and this still does not help, then have the administrator also merge the needed .reg file for the listed file extension or protocol below while logged into their administrator account.

7. When finished, you can delete the downloaded .reg file if you like.




Default Windows 8 and 8.1 File Associations:

Note   Note
To download all available default file extensions in the table below in one ZIP folder, click on the Download button below and save the ZIP file to your desktop. Open the ZIP file, and extract (drag and drop) to your desktop any .reg file for file extensions you want to use. You can now pick up at step 3 above.

I have the same problem but is when i try to open the local drive C and the others. what kind of file can i download?

Hello John, and welcome to Eight Forums.

Could you please provide more details on what problem you are having when you try to open drives?

If you mean the you get a program not associated type error, then you could download and merge the .reg file for the listed drive option to restore it's default associations and registry entries to hopefully fix this for you.

Hope this helps, :)

I had the same issue on my Windows 8 (x64bit) desktop where .bat files were opening my text editor.
I tried all the fixes I could find on the internet but no luck. I was finally able to diagnose the problem by associating .bat files with a unique exe like "rumplestiltskin123.exe". Then I searched registry for all occurrences of "rumplestiltskin123".
It turns out I needed to remove the following roaming registry key which is not included in your downloadable reg files for each filetype.
This is the key that I needed to delete:-

[-HKEY_CURRENT_USER\Software\Microsoft\Windows\Roaming\OpenWith\FileExts\.bat\UserChoice]
 
Hello 8penguin, and welcome to Eight Forums.

If you like the .bat download in the tutorial does this for you if you should ever need to reset it's associations back to default again. :)

Thanks for the quick reply Brink! No I have already attempted to use the downloadable reg file for .bat from this thread Whilst it removes one of the .bat reg keys it doesnt removes the "roaming" key I mentioned in my previous post which is slightly different.

HKEY_CURRENT_USER\Software\Microsoft\Windows\Roaming\OpenWith\FileExts\.bat\UserChoice

Only by removing this specific key was I able to fix the problem.
 
Odd. Did you restart the PC after merging the .reg file for .bat?

It should have changed that location as well after a restart.
 
New "Links" Folder

I'd like to use the link (.lnk) but when I click on it it just goes to the main forum page on this website.
The problem I'm having is that I can't put anything in my "favorites" folder in windows explorer. I learned this is because I need to recreate a new "links" folder for the shortcuts to go in, but I don't know how to do that - is that what this is? Will this help solve my problem?
 
Hello Regebush, and welcome to Eight Forums.

It depends on what is happening with your .exe files? Please post back with more details about your issue with them.

In the mean time if you like, you could download and merge the .reg file for the listed .exe option in the tutorial on the first page of this thread. It will restore the default associations and registry entries for .exe files.

Hope this helps for now, :)

Hello Stu, and welcome to Eight Forums. :)

The .wi file type does not have a default program set to it by default in Windows 8, so there are not any default registry entries.

If you like, I could create a .reg file that will unassociate .wi files to no longer have a default program set to open them with.
 
That would be great, I did wonder why the miss- association did not seem to cause any problem, but like it back to normal, I just like things that way, unfortunately I did not remove the tick from the box and the WI files now are associated with note pad.
Many thanks for such a speed reply. this seems a really interesting site that I stumbled across.

I do not think you understand my concern. Can you please try clicking on the .exe link on the first page and you will see what I mean.
 
Sorry about that Regebush. I did misunderstood what you meant. :(

The .exe download link has been fixed. Please try downloading it again now.
