Notes on Encrypting Your Data (Infineon TPMProfessional Package)

Before encrypting your data with Infineon TPM Professional Package, read the

following precautions for correct use.

Notes on encrypting the operating system files or program files

If the operating system files or the software application files are encrypted using the

Encrypting File System (EFS) in conjunction with the Trusted Platform Module (TPM),

you may not be able to log onto Windows or operate the software applications properly.

Do not encrypt the Windows folder, the Program Files folder, and files in those

folders.

Observe the following when using the EFS.

Do not change the following default settings under Files and Folders on the View

tab in the Folder Options window.

Don’t show hidden files, folders, or drives (selected by default)

Hide protected operating system files (Recommended) (selected by

default)

Do not change file attributes (read only, hidden, and system), unless necessary.

Do not encrypt the Users folder and the account folder in the Users folder all

together.

Notes on encrypting key files or files on the Personal Secure

Drive

If you encrypt files in the following folders using the EFS under these conditions; the TPM

software has been installed on your VAIO computer; the TPM has been initialized; and the

EFS has been enabled during the user initialization, the TPM software becomes unstable

and your encrypted data cannot be restored.

Do not encrypt the files using the EFS or change folder and file attributes in the following

folders.

With the TPM software installed and initialized, the files cannot be encrypted because they

have system attributes.
