About Software Modules Update
Kaspersky can issue update packages for Kaspersky Security for Windows Server modules. The update packages can be urgent (or critical) or planned. Critical update packages repair vulnerabilities and errors; planned packages add new features or enhance existing features.
Urgent (critical) update packages are uploaded to Kaspersky's update servers. Their automatic installation can be configured using the Software Modules Update task. By default, Kaspersky Security for Windows Server runs the Software Modules Update task on a weekly basis on Fridays at 4:00 PM (according to the regional time settings of the protected device).
Kaspersky does not publish planned update packages on its update servers for automatic update; these can be downloaded from the Kaspersky website. The Software Modules Update task can be used to receive information about the release of scheduled Kaspersky Security for Windows Server updates.
Critical updates can be retrieved from the Internet and applied to each protected device, or one protected device can be used as an intermediary by copying all updates onto it and then distributing them to the network protected devices. In order to copy and save updates without installing them, use the Copying Updates task.
Before updates of modules are installed, Kaspersky Security for Windows Server creates backup copies of the previously installed modules. If the software module update process is interrupted or results in an error, Kaspersky Security for Windows Server will automatically return to using the previously installed software modules. Software modules can be rolled back manually to the previously installed updates.
During the installation of downloaded updates, the Kaspersky Security Service automatically stops and then restarts.
