Note: The user name and password properties can be managed by Active Directory. Since the user name and password must be encrypted when used as an application property, an administrator can use a Lenovo supplied utility called MapDrv to generate encrypted strings for the user name and password using a software key. For additional information about the MapDrv utility, see "Map Drive utility" on page 80. The following keys are used to store the user name and password: HKLM\Software\Lenovo\MND\TVSUAPPLICATION\UNC= HKLM\Software\Policies\Lenovo\MND\TVSUAPPLICATION\UNC= HKLM\Software\Lenovo\MND\TVSUAPPLICATION\Pwd= If an Active Directory policy is used, these values are stored at: HKLM\Software\Policies\Lenovo\MND\TVSUAPPLICATION\UNC= HKLM\Software\Policies\Lenovo\MND\TVSUAPPLICATION\User= HKLM\Software\Policies\Lenovo\MND\TVSUAPPLICATION\Pwd= 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: v 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. Examples of critical packages: - A hard disk drive firmware update that if not applied could result in hard disk drive failure. - A BIOS upgrade that if not applies will result in system lags. - A software patch to an application that if not applied could result in data loss on your system. v Recommended packages are recommended by Lenovo and will ensure your system is working at optimal performance. This severity level should be the default for most drivers. Examples of recommended packages: Chapter 4. Working with System Update 41
