Restore and Reset File Association in Windows Vista Back to Original Default
Windows Vista allows user to change and set default program association for most kind of file extension type via Control Panel’s “Set Associations” or “Set Default Programs” under “Default Programs” link. However, there is no option or way to reset or restore the file type or file extension association to back to original default the is configured in factory-pre-installed or freshly installed Windows Vista.
List of programs available under “Set Default Programs” link, such as Internet Explorer, Microsoft Office Outlook, Windows Calender, Windows Mail, Windows Media Player and Windows Photo Gallery has defined their own default supported file extensions, types and protocols. And, user can easily set the program as the default program to use to open all file types and protocols it can open. Even so, it may not be the default file association that configured in Windows Vista originally.
Unless user remembers and knows the original file association and change the default program for the kind of file type accordingly using the graphical user interface (GUI) in Control Panel, else here’s another workaround to restore and reset the file association to the default Windows Vista version of file association.
- Click Start Menu, and then type regedit in the Start Search and press ENTER.
- Navigate to the following registry branch:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Explorer\FileExts\[ext]
Replace the [exe] with the actual file extension that you want to restore its file type association to revert back to original Windows Vista default. If you unsure, simply browse through all the sub-key under FileExts.
- Delete the sub-key named UserChoice.
- Exit from Registry Editor.
Windows Vista will now use original file associations that comes built into system for the particular file extensions with “UserChoice” deleted. However, the trick is not foolproof, especially if the other related system registry keys for the particular extension have been corrupted or broken. In such cases, it may be necessary to fix the file association by restoring its registry settings.

Thanks a BUNCH! I had to restore my .WAgame file to open with WA.exe because I messed around and clicked on open with notepad for some reason. Windows 7 wouldn’t let me set it back to WA.exe, but this trick works! Oh and for anyone saying it doesn’t work, maybe you should start back a step one and give it another shot. I can prove that it works! Lawl! XD

Dude,
You saved my life. Stupid Vista and its default programs. I couldn’t open this one program because it kept asking for the application and when it did i could not select the right one. Once again, thanks and i appreciate it.

Wow, this was totally unhelpful. There is no such sub-Key called User Choice.

Thank you very much, your instructions worked! Your guidance is very much appreciated!

I was actually very unsure to delete the sub-key User choice because I cannot backup the sub-key (in case, it doesn’t work I can restore it back). However, it works.. Thx. lol

I cannot even open regedit. It opens the box that says “This file does not have a program associated with it for performing this action. Create an association in the Set Association Control Panel.” Somebody, please help me.
