Configuring System Update
Configurations for System Update can be done through the registry, Active
Directory
®
, or the start.reg file. If you are configuring just one system, you can use
the registry to configure System Update. If you are configuring multiple systems,
you can use Active Directory to configure policies for System Update. If your
enterprise does not use Active Directory, Lenovo provides the start.reg file that you
can configure and then deploy to multiple systems. For additional information
about each configuration method, see the following sections:
v “Configuring System Update with the registry”
v “Configuring System Update with Active Directory” on page 28
v “Configuring System Update with start.reg” on page 35
Configuring System Update with the registry
To edit registry configurations, close the System Update application. If System
Update is running while changes are made in the registry, the old registry entries
will be recovered. After the first launch of System Update, the configurable items
for System Update that can be modified are in the following registry locations:
