|Introduction||A BIOS password is the authentication information required to log in to a PC's BIOS before it boots up.||A Windows password is the password a user needs to log into Windows. There is normally an administrator account to manage the entire PC and several user accounts for individual users.||Encrypting File System (EFS) is a feature of Windows that you can use to store information on a hard disk in an encrypted format. It is the strongest protection that Windows provides to secure your information.||The HDD password protects all data stored on the hard disk, keeping the data safe from being read or overwritten by unauthorized users.||The TPM creates cryptograhic keys and encrypts them so that they can only be decrypted by that particular TPM. This allows the hard disk drive to be tied to a particular device which has TPM embedded.|
