The SMS_TaskSequence Windows Management Instrumentation (WMI) class is an SMS Provider server class, in Configuration Manager, that represents an operating system deployment task sequence.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties.

Syntax

Class SMS_TaskSequence  
{  
      String SchemaVersion;  
      SMS_TaskSequence_Step Steps[];  
};

Methods

The following table shows the methods in SMS_TaskSequence.

Method	Description
ExportXml Method in Class SMS_TaskSequence	Exports task sequence XML in a format that is suitable to use on another site.
LoadFromXml Method in Class SMS_TaskSequence	Loads a task sequence into WMI objects from XML.
SaveToXml Method in Class SMS_TaskSequence	Serializes a task sequence from WMI objects to XML.

Properties

SchemaVersion
Data type: String

Access type: Read/Write

Qualifiers: None

The version of the task sequence schema. The default version number is 3.00.

Although this property is designated as read/write in WMI, your application should not change it. The schema version must match the version that is detected by the client, or the client does not run the task sequence.

Steps
Data type: SMS_TaskSequence_Step Array

Access type: Read/Write

Qualifiers: None

SMS_TaskSequence_Step Server WMI Class objects representing steps and conditions in the task sequence.

Remarks

Class qualifiers for this class include:

Dynamic
Provider("TaskSequenceProvider")

For more information about both the class qualifiers and the property qualifiers included in the Properties section, see Configuration Manager Class and Property Qualifiers.

A task sequence is a series of steps and conditions that are processed during operating system deployment.

A step in the task sequence is usually an action, represented by the SMS_TaskSequence_Action Server WMI Class or a derived class. A task sequence step can also be a set of actions in a group, represented by SMS_TaskSequence_Group Server WMI Class. For more information, see SMS_TaskSequence_Step Server WMI Class.

Task sequence steps are managed using WMI. The sequence steps are processed in order and can have conditions associated with them that determine how the action, or group of actions, is processed. For more information, see Operating System Deployment Task Sequence Object Model.

Your application uses SMS_TaskSequence objects through a SMS_TaskSequencePackage Server WMI Class object, which supports a Sequence property to wrap the task sequence in the database. The application sets up a new task sequence by calling the SetSequence Method in Class SMS_TaskSequencePackage and accesses an existing task sequence using the GetSequence Method in Class SMS_TaskSequencePackage. For more information about working with a task sequence, see How to Create an Operating System Deployment Task Sequence and How to Create an Operating System Deployment Task Sequence Package.
