In the Configuration File pane, click the Enhanced Write Filter package to show the components.
Click the SystemRestore-Main component.
In the Settings pane, click the Filter view by drop-down combo box, select 4 Specialize.
Change the value of the DisableSR setting to 1. A value of 0 enables System Restore and creates restore points according to events and a schedule. This is the default value. A value of 1 specifies that no more restore points will be created. This limits the ongoing usefulness of System Restore on the computer.

Add the following registry key to your run-time image:
