Update privileges allow client users to configure their own update settings.
Users with this privilege can update components on demand by right-clicking the OfficeScan icon on the system tray and selecting Update Now. You can configure clients to use proxy settings during "Update Now". See Automatic Proxy Configuration for details.
This privilege allows clients users to enable/disable scheduled update. Although users have the privilege to enable/disable scheduled update, they cannot configure the actual schedule. You will have to specify the schedule in Updates > Networked Computers > Automatic Update > Schedule-based Update.
