    Hi Brink,

    Unfortunately that trick didn't work for me! I tried downloading .iso reg file to unassociate iso files from Diamond tools lite, unsuccessfully. Im wondering if you can help me to figure it out the problem!

    Best regards,

    Hello Mike, and welcome to Eight Forums.

    Double check to see if the program may have settings of it's own for this that may be overriding the association.

    Did you restart the PC and fully approving the merge of the .reg file?

    Hello again Brink! Apparently there is nothing wrong. Windows prompt me a message saying that the registry entry was successfully changed, but with no actual results. In fact i was able to unassociate it following the steps on this video: Unassociate File Type in Windows 8 any version - YouTube. The only problem is that the .iso file icon is now a blank sheet and i cant set it back to what it was!

    Yep, if you unassociate a file extension, it is then set to not have any program to open it with by default.

    Did you restart the PC after merging the .reg file for the ISO download to apply the associations for it?

    Yes, but it didn't work. Now my only problem is the file icon, that i cant set back to default( The blank sheet with the little disk in it). Well, my main issue is solved, so i think ill just give up trying to change this icon. If you have any other ideas, let me know (:

    The default icon for ISO files is located in the DefaultIcon registry key below.

    HKEY_CLASSES_ROOT\Windows.IsoFile\DefaultIcon

    (Default) data value = %SystemRoot%\System32\imageres.dll,-5205

    I took a look to mine and it looks exactly like that! The data value is the same discribed above. I'll try downloading your .reg file for the last time and see if it works. Thanks for all the help Brink! This is a great windows 8 forum! See ya =)

    Best Regards,

    The .reg file for the listed ISO should restore that.

    I ran into the same problem and SOLVED it.

    Background:
    - Migration from Windows7 Pro-x32 to Windows 8 Pro-x32

    Scenario:
    - Win8 refused to associate certain audio/video file extensions (specifically flv, avi, mp3, mp4, m4v, mov, mpg, mpeg) with VideoLAN VLC media player while others (e.g. mkv) were associated.

    Solution:
    1. open regedit [I used > Windows Registry Editor Version 5.00]
    2. navigate to > HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts
    3. backup the FileExts folder (right-click > Export)... just to be safe
    4. delete the extensions that refuse to associate with your program (right-click > Delete)
    5. open: Control Panel > All Control Panel Items > Default Programs > Associate a file type or protocol with a program
    6. for each extension you just deleted in the registry: Choose it > click on: Change program... (grey button on the right) > choose your program
    7. DONE! The files are associated immediately, no system restart required.

    Good luck!
    Let me know if this solved your issue.
