hi all.. I've got a sony viao ultra book running win8.1. My user account is set to open with a four digit pin. Unfortunately, although I know the PIN number, I have forgotten both the user and the admin password. So I can't load any new software as it asks me for the admin password every time. Can anyone explain how to retrieve both passwords? Thanks in advance
