Lenovo System Update Solution (Deployment Guide) - Manual (Page 47)

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=<network share>
HKLM\Software\Policies\Lenovo\MND\TVSUAPPLICATION\UNC=
<network share>
HKLM\Software\Lenovo\MND\TVSUAPPLICATION\Pwd=
<encrypted password>
If an Active Directory policy is used, these values are stored at:
HKLM\Software\Policies\Lenovo\MND\TVSUAPPLICATION\UNC=
<network share>
HKLM\Software\Policies\Lenovo\MND\TVSUAPPLICATION\User=
<encrypted username>
HKLM\Software\Policies\Lenovo\MND\TVSUAPPLICATION\Pwd=
<encrypted password>
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:
