Win32_ServiceSpecification class

The Win32_ServiceSpecification WMI class represents a service that is to be installed with an associated package.

Note  For more information about support or requirements for installation on a specific operating system, see Operating System Availability of WMI Components.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties and methods are in alphabetic order, not MOF order.

Members

The Win32_ServiceSpecification class has these types of members:

Methods

The Win32_ServiceSpecification class has these methods.

MethodDescription
Invoke

Evaluates a specific check. The details of how the method evaluates a specific check in a CIM context are described by the non-abstract CIM_Check subclasses.

 

Properties

The Win32_ServiceSpecification class has these properties.

Caption
Data type: string
Access type: Read-only

Short textual description of the object—a one-line string.

CheckID
Data type: string
Access type: Read-only

Identifier used together with other keys to uniquely identify the check.

CheckMode
Data type: Boolean
Access type: Read-only

Whether or not the condition is expected to exist in the environment. When TRUE, the condition is expected to exist, for example, a file is expected to be on a system, so the Invoke method is expected to return TRUE.

Dependencies
Data type: string
Access type: Read-only

List of names of services or load ordering groups that the system must start before this service. Names in the list are separated by nulls. If the service does not have dependencies, then NULL or an empty string is returned. Dependency on a group means that this service can run if at least one member of the group is running after an attempt to start all members of the group.

Description
Data type: string
Access type: Read-only

Description of an object.

DisplayName
Data type: string
Access type: Read-only

Service identifier that the user interface programs use.

ErrorControl
Data type: sint32
Access type: Read-only

Action that the startup program takes if the service does not start during startup. One of the following error control flags must be specified. Add the value 0x08000 to the following flags to specify that the overall install fails if the service cannot be installed.

ValueMeaning
0x00000000

Logs the error and continues with the startup operation.

0x00000001

Logs the error, displays a message box, and continues the startup operation.

Logs the error if it is possible, and the system is restarted with the last configuration that is known to be good. If the last good configuration is being started, the startup operation fails.

 

ID
Data type: string
Access type: Read-only

Unique key that identifies the service specification item within its product.

LoadOrderGroup
Data type: string
Access type: Read-only

Name of the load ordering group of which this service is a member.

Name
Data type: string
Access type: Read-only

Name used to identify the software element.

Password
Data type: string
Access type: Read-only

Password associated with StartName.

ServiceType
Data type: sint32
Access type: Read-only

Bit flags that specify the type of service. One of the following service types must be specified.

ValueMeaning
