I've uninstalled the 3.5 version because I had the 3.7 version installed already.

Little question, if I want the password option back in again, can I safely use the incudes/adminfunctions.php change from the 3.5 version, or is the code in 3.7 changed in such way I can't use that anymore?
If that's the case, is it possible to supply the correct code to put it in myself?
