Once payment is completed you will immediately receive an e-mail with “Password/Unlock Key + instructions”, this password will allow you to reset the Administrator/System passwords and set your own if desired, reconfigure boot options, etc.
IMPORTANT: Do not type anything until you have received the Unlock Key (password), as Hint Code will change every 3 incorrect passwords. At second incorrect password force computer shutdown and try again.
