Step 1. Defining whether to reduce traffic

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, you can disable the Download express installation files option.

If this option is selected, express update files are downloaded when running the task. By default, this option is not selected.
