Customizing update packages for client computers
For enterprises that need to create custom update packages for client computers, use both System Update
and Update Retriever to manage the update process. As an administrator, you can use Update Retriever to
download selected update packages from the Lenovo Help Center to a repository folder on a network share.
You can use Update Retriever to edit an existing package or create a new package in the repository folder.
Update Retriever uses an XML descriptor file to define when an update package is relevant and how to install
the update package. For example, you can create an XML descriptor file that enables a specific update
to be downloaded and installed on a client computer depending on the version of the software already
installed or existing hardware devices found in the system. After using Update Retriever to customize update
packages to fit the needs of your enterprise, import the update packages into the repository folder on the
network share using Update Retriever.
On client computers, use System Update to search the network share repository folder for update packages.
System Update can then download and install relevant packages from the network share repository folder to
client computers.
The following illustration shows the communication path among the Lenovo Help Center, System Update,
and Update Retriever when using Update Retriever to manage the update process:
