Default File Type Associations - Restore

Restore Default Vista File Extension Type Associations

information   Information
This will allow you to restore the default registry entries and program associations for the Vista file extension type of your choice.

Note   Note
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 in the tutorial below, will restore that file extension back to default for all of these items above.

If the file extension type you need to restore is not listed below yet, then please post a request for it. I'll be happy to add it to the list. :)

warning   Warning
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.

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

These default file extensions should only be used in Vista.



Here's How:

1. Click on the file extension type link listed below for the one that you wish to restore to default to download it's .zip file.

2. Save the .zip file to your desktop.

3. Open the downloaded .zip file, then extract the .reg file to the desktop.

4. Right click on the extracted .reg file and click on Merge.
Tip   Tip
If you do not see a Merge option when you right click on the REG file, then you will need to check in Default Programs to set the reg file extension to have it's Current Default program set as Registry Editor (C:\Windows\regedit.exe). Afterwards, try merging the REG file again.



5. If prompted, click on Run, Continue (UAC), Yes, and OK.
NOTE: If you are logged in a standard user account, then you will get a Cannot import type error. Just click on 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 association of the file extension though.

6. When done, you can delete the downloaded .zip and .reg files on the desktop if you like.

7. Log off and log on, or restart the computer to fully apply.

The file is now recognized as Type: Microsoft Office Publisher Document.

However, the icon is still generic document and when i double click or try to open the document I get error message: This action is only valid for products that are currently installed.

Publisher is installed.

I try to Open With and although MS Publisher is the recommended programs when I click OK nothing happens.
 

My Computer

Hmm, ok. Running the Publisher installer again should allow you to do a repair install to fix it then hopefully. :)

You guy are all verey bright and i'm no dummie but if it weren't for people like all of you, I'd be in a world of trouble. I really appreciate that there exists purists who enjoy helping others. Thank you guys, I'm good to go for now.

Do you have one for .ani files? Because for some reason, after I tried to click on a program through "Open With" I could no longer get a preview of any ani files, except through the program that I selected, but I want to be able to preview the file in the folder without having to actually open the file.
 

My Computer

Hello DarkRemorse, and welcome to Vista Forums.

ANI added. :)

my .html files, specifically as they relate to my web browser, are blank.

I'm running firefox as my primary browser, I download alot of fanfiction as .html, so, bearing in mind in the past, these files have had a firefox emblem on them, then one day they suddenly dont.

this has happened in the past, and while clean installs fix matters, inevitably it happens again.

for the record I can still access and use the files properly, its just the appearance of the icons that refuses to work.

dunno what the deal is..

Hello xraiderv1,

This tutorial would only restore .html files to be opened with the default Internet Explorer.

If you wanted .html files to remain to be opened with Firefox, then open Default Programs and check make sure that Firefox is set to be the default program of all it's file types.

If that doesn't restore the icon, then rebuilding the icon cache may.

Hope this helps,
Shawn

ran the manual tutorial, it didnt work. I appreciate such a well laid out and easy to understand guide, thank you for that.

I can still open my html files, and there doesnt appear to be anything else wrong, maybe this is a harmless cosmetic issue?

checked the associations, its still set to open with firefox.... *scratches head*

first thing I tried, though just now, I tried it again after running that icon cache tutorial to see if it made a difference.

files open just fine, every time, without fail, its just the icons that refuse to play nice, if you will.

Ok. See if downloading and merging the REG file below may restore it back to the icon below. You may need to restart the computer afterwards to apply though.

Well, that stinks.

As a test, uninstall and reinstall Firefox, then make Firefox the default program again to see if that restores the icon.

Ok, let's go the manual route to see if that may work for you instead. :)

  • Download and save the ZIP file below to your desktop.
  • Extract (drag and drop) the icon file from the ZIP file to your desktop.
  • Unblock the icon file.
  • Move the icon file to inside your C:\Program Files (x86)\Mozilla Firefox folder.
  • Download and save the REG file below to your desktop.
  • Merge the REG file to make this icon the default one for .html files.
  • Restart the computer to apply.
