The IAutomaticUpdatesSettings interface defines the following properties.
|NotificationLevel||Gets and sets how users are notified about Automatic Update events.|
|ReadOnly||Gets a Boolean value that indicates whether the Automatic Update settings are read-only.|
|Required||Gets a Boolean value that indicates whether Group Policy requires the Automatic Updates service.|
|ScheduledInstallationDay||Gets and sets the days of the week on which Automatic Updates installs or uninstalls updates.|
|ScheduledInstallationTime||Gets and sets the time at which Automatic Updates installs or uninstalls updates.|
Note Windows 8, Windows 8.1, Windows Server 2012, and Windows Server 2012 R2 provide only limited support for ScheduledInstallationDay and ScheduledInstallationTime. If the computer has been configured through Group Policy to use a scheduled installation day and time, the ScheduledInstallationDay and ScheduledInstallationTime properties return this scheduled day and time. If the computer hasn't been configured through Group Policy in this way, the ScheduledInstallationDay and ScheduledInstallationTime properties return default and unreliable values. If you try to modify the scheduled installation day and time on these operating systems, ScheduledInstallationDay and ScheduledInstallationTime appear to succeed but have no effect.
