System Center Guide

Tip:

You must enable each program that is associated with a Task Sequence application installation (including the SCCM client) to be available during Task Sequence execution without an Advertisement. To do so, just select the properties for the appropriate program (most commonly Per System Unattented Installation) and tick the checkbox at the bottom of the resulting tab.

If this item isn’t selected, all applications intended to be installed during the Task Sequence will fail. No Microsoft Updates will be installed and the User State will not be migrated as the Configuration Manager client will not be present.
