Select and Apply Rollbacks

The Platform Rollback screen displays a list of available rollback components.

Select the check box of each rollback image that you want to apply to

the system.

To compare the version of the rollback image with the version currently

installed on the system, compare the versions in the

Current

and

fields.

NOTE: An ellipsis (...) appearing at the end of the displayed field indicates

that the full value is not displayed. To view more detailed information,

NOTE: The system reboots after the update process is complete.

When applying more than one update, the system may need to reboot

between updates. In this case, the system boots directly into USC - LCE and

continues the update process. This is an unattended update process.

Updating Devices That Affect Trusted Platform Module Settings

If BitLocker protection is enabled on your system, updating certain

components requires you to enter a recovery password or insert a USB flash

drive containing a recovery key during the next system boot. This situation

occurs only if the Trusted Platform Module (TPM) security setting is set to

On with Pre-boot Measurements.

NOTE: For information on how to set TPM settings, see the BIOS User Guide

available at support.dell.com/manuals.

When USC - LCE detects that TPM security is set to On with Pre-boot

Measurements, a warning message displays indicating that certain updates

require the recovery password or USB flash drive with the recovery key.

The warning message also indicates which components affect the BitLocker.

You can choose either not to update or to roll back those components by

navigating to the Select Updates screen and deselecting the check boxes for

the components.
