The Perform Windows Update synchronization task is only available under the Vulnerability and Patch Management license.
The Perform Windows Update synchronization task is required if you want to use the Administration Server as a WSUS server. In this case, the Administration Server downloads Windows updates to the database, and provides the updates to Windows Update on client devices, in the centralized mode through Network Agents. If the network does not use a WSUS server, each client device downloads Microsoft updates from external servers independently.
The Perform Windows Update synchronization task only downloads metadata from Microsoft servers. Kaspersky Security Center downloads the updates when you run an update installation task and only those updates that you select for installation.
When running the Perform Windows Update synchronization task, the application receives a list of current updates from a Microsoft update server. Next, Kaspersky Security Center compiles a list of updates that have become outdated. At the next start of the Find vulnerabilities and required updates task, Kaspersky Security Center flags all outdated updates and sets the deletion time for them. At the next start of the Perform Windows Update synchronization task, all updates flagged for deletion 30 days ago are deleted. Kaspersky Security Center also checks for outdated updates that were flagged for deletion more than 180 days ago, and then deletes those older updates.
When the Perform Windows Update synchronization task completes and outdated updates are deleted, the database may still have the hash codes pertaining to the files of deleted updates, as well as corresponding files in the %AllUsersProfile%\Application Data\KasperskyLab\adminkit\1093\.working\wusfiles files (if they were downloaded earlier). You can run the Administration Server maintenance task to delete these outdated records from the database and corresponding files.
To create the Perform Windows Update synchronization task:
The Add Task Wizard starts. Follow the steps of the Wizard.
When Kaspersky Security Center synchronizes updates with Microsoft Windows Update Servers, information about all files is saved in the Administration Server database. All files required for an update are also downloaded to the drive during interaction with the Windows Update Agent. In particular, Kaspersky Security Center saves information about express update files to the database and downloads them when necessary. Downloading express update files leads to decreased free space on the drive.
To avoid a decrease in disk space volume and to reduce traffic, disable the Download express installation files option.
If the All applications check box is selected, updates will be downloaded for all existing applications, and for all applications that may be released in the future.
If the All categories check box is selected, updates will be downloaded for all existing updates categories, and for all categories that may appear in the future.
