Settings Management Infrastructure (SMI) is a schema used to define mutable operating system settings. A mutable setting is a variable setting in which value of the setting can be changed, either by other components or by user or administrator. For e.g., user-preferred fonts & font colors are mutable settings. Mutable settings can reside in any settings store in OS, such as registry, .ini files, or some other public store, such as IIS Metabase or WMI repository. These settings’re exposed to OEMs & Corporations to enable customization and make deployment of OS easier. In Standard 7, these settings’re included with each component in a Feature Package. In ICE, once you select a feature package to be included in your answer file, you’ll be presented with a list of settings that correspond to every component in package you selected. A “pass” is a certain phase during an automated unattend setup in which unattend settings’re applied. A setting could apply to one or more passes. There’re 2 types of unattend passes: online and offline passes. Offline passes are staged with an OS image that isn’t currently running. Offline Servicing is an offline pass. Online passes occur on an actively running OS and are used to apply settings and packages during Windows Setup. Following passes are online passes: Generalize, Specialize, Audit System, Audit User and OOBE System.
