 From http://superuser.com/questions/49615/how-do-you-remove-a-default-program-association-for-file-types-in-windows-7

 Find the file extension in question under this key in the registry:
 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts

 Deleting the sub-key with the same name as the extension you want to un-associate will delete the default program association. You'll have to kill and restart explorer.exe for this to take effect.
 You may also need to remove the same sub key from HKEY_CLASSES_ROOT as well.
