The List Fields makes several modifications to the registry.
Note: Some of the settings are obfuscated, to keep your registration information a little bit more secure for prying eyes. This information is at the present time not possible to recreate in a manual matter.
Another thing to note; If you select to install List Fields for all users, the following keys and values below should be placed in the HKEY_LOCAL_MACHINE\Software hierarchy. If you just want to install for the current user, place keys and values in the HKEY_CURRENT_USER\Software hierarchy. Read much more about that here.
Below you see an image of the registry content:
