Deprovision and Uninstall Dell Data Protection | Access

If DDP|A is installed now or has been installed in the past on your computer, before installing the Encryption client, SED,

or Advanced Authentication, you must deprovision the DDP|A-managed hardware and then uninstall DDP|A. If DDP|A

has not been used, you may simply uninstall DDP|A and restart the installation process.

Deprovisioning DDP|A-managed hardware i

ncludes the fingerprint reader, smart card reader, BIOS passwords, TPM, and

the Self-Encrypting Drive.

NOTE:

If running DDP|E encryption products, stop or pause an encryption sweep. If running Microsoft BitLocker, suspend the encryption

policy. Once DDP|A is uninstalled and Microsoft BitLocker policy is unsuspended, initialize the TPM by following the instructions

located at

http://technet.microsoft.com/en-us/library/cc753140.aspx

Deprovision DDP|A-Managed Hardware

Launch DDP|A and click the

Advanced

tab.

Select

Reset System

. This will require that you enter any provisioned credentials to verify your identity. After DDP|A

verifies the credentials, DDP|A will perform the following actions:

• Remove all provisioned credentials from Dell ControlVault (if present)

• Remove Dell ControlVault owner password (if present)

• Remove all provisioned fingerprints from integrated fingerprint reader (if present)

• Remove all BIOS passwords (BIOS System, BIOS Admin, and HDD passwords)

• Clear the Trusted Platform Module

• Remove the DDP|A Credential Provider

Once the computer is deprovisioned, DDP|A reboots the computer

to restore the Windows default credential provider.

Uninstall DDP|A

Once the authentication hardware is deprovisioned, uninstall DDP|A.

Launch DDP|A and perform a Reset System.

This will remove all DDP|A managed credentials and passwords and will clear the Trusted Platform Module (TPM).

When the uninstall finishes, click

to restart.

NOTE: If using a self-encrypting drive, removing DDP|A will also unlock the SED and remove the Preboot Authentication.
