Working with license agreements
Upon searching for update packages, System Update will provide update packages to download and install.
Update packages can contain license agreements. If you store update packages in a repository, you can
save time and effort by using silent command scripts and by configuring System Update to recognize
these license agreements automatically. To configure System Update to recognize license agreements
automatically, set the following registry value to YES:
HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\System Update
\Preferences\UserSettings\General\IgnoreLocalLicense
Note: Using silent command scripts to recognize license agreements works only if you use a repository
to store update packages. If you obtain packages directly from the Lenovo Help Center Web site, silent
command scripts will not be effective.
Using System Update
When using System Update to search for update packages, System Update will display search results in four
categories: Critical, Recommended, Optional, and Extra. This categorization also defines the severity level
of the package. For a description of each category, see the following:
• Critical packages are considered mandatory for your system to function properly. Failure to install these
packages could result in data loss, system malfunction, or hardware failure. You can choose to have
critical updates downloaded and installed automatically on a scheduled basis. A critical package can
be, for example:
– A hard disk drive firmware update that if not applied could result in hard disk drive failure.
– A BIOS upgrade that if not applied will result in system lags.
– A software patch to an application that if not applied could result in data loss on your system.
• Recommended packages are packages recommended by Lenovo to ensure your system working at
optimal performance. This severity level should be the default for most drivers. A recommended package
can be, for example:
– A video driver that corrects an issue that may cause blue screen issues.
– A BIOS update that contains minor fixes that may impact a small group of customers.
– A power management driver that will allow a mobile system to get the most out of its battery life.
• Optional packages will improve your computing experience, but are not necessary. An optional package
can be, for example:
– A tool that enables you to migrate files from one system to another such as the ThinkVantage® Rescue
and Recovery® program. The Rescue and Recovery program is not needed for your system to operate,
but provides benefit if you choose to install it.
– Any BIOS or driver upgrade that has been updated only to support newer systems and contains no
fixes.
