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. Here is another workaround to restore or reset the file association to the defaults in Windows 7.

1. Press the Windows key + r (or Click Start Menu, and then type regedit)

2. Navigate to the following registry branch in registry:

HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Explorer\FileExts\
