CIM_Thread class
The CIM_Thread class represents the ability to execute units of a process or task, in parallel. A process can have many threads, each of which is weak to the process.
Important
The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of its inherited properties. Properties are listed in alphabetic order, not MOF order.

Properties
The CIM_Thread class has these properties.
-
Caption
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (64), DisplayName ("Caption")
Short textual description of the object.
This property is inherited from CIM_ManagedSystemElement.
-
-
CreationClassName
-
Name of the class or subclass used in the creation of an instance. When used with other key properties of the class, this property allow all instances of the class and its subclasses to be uniquely identified.
-
CSCreationClassName
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: Propagated ("CIM_Process.CSCreationClassName"), Cim_Key, MaxLen (256)
Scoping computer system's creation class name.
-
-
CSName
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: Propagated ("CIM_Process.CSName"), Cim_Key, MaxLen (256)
Scoping computer system's name.
-
-
Description
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: DisplayName ("Description")
Textual description of the object.
This property is inherited from CIM_ManagedSystemElement.
-
-
ExecutionState
-
-
Data type: uint16
-
Access type: Read-only
Indicates the current operating condition of the thread.
-
-
Unknown (0)
-
Other (1)
-
Ready (2)
-
Running (3)
-
Blocked (4)
-
Suspended Blocked (5)
-
Suspended Ready (6)
Handle
Identifier for the thread.
InstallDate
-
Data type: datetime
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5"), DisplayName ("Install Date")
Date and time the object was installed. This property does not need a value to indicate that the object is installed.
This property is inherited from CIM_ManagedSystemElement.
KernelModeTime
-
Data type: uint64
-
Access type: Read-only
-
Qualifiers: Units ("milliseconds")
Time, in kernel mode, in 100 nanosecond units. If this information is not available, a value of 0 (zero) should be used.
For more information about using uint64 values in scripts, see Scripting in WMI.
Name
-
Data type: string
-
Access type: Read-only
-
Qualifiers: DisplayName ("Name")
Label by which the object is known. When subclassed, this property can be overridden to be a key property.
This property is inherited from CIM_ManagedSystemElement.
OSCreationClassName
-
Data type: string
-
Access type: Read-only
-
Qualifiers: Propagated ("CIM_Process.OSCreationClassName"), Cim_Key, MaxLen (256)
Scoping operating system's creation class name.
OSName
-
Data type: string
-
Access type: Read-only
-
Qualifiers: Propagated ("CIM_Process.OSName"), Cim_Key, MaxLen (256)
Scoping operating system's name.
Priority
-
Data type: uint32
-
Access type: Read-only
Urgency for execution of a thread. A thread can have a different priority than its owning process. If this information is not available for a thread, a value of 0 (zero) should be used.
ProcessCreationClassName
-
Data type: string
-
Access type: Read-only
-
Qualifiers: Propagated ("CIM_Process.CreationClassName"), Cim_Key, MaxLen (256)
Scoping process's creation class name.
ProcessHandle
-
Data type: string
-
Access type: Read-only
-
Qualifiers: Propagated ("CIM_Process.Handle"), Key, MaxLen (256)
Scoping process's handle.
Status
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (10), DisplayName ("Status")
Current status of the object. This property is inherited from CIM_ManagedSystemElement.
Values include the following:
OK ("OK")
Error ("Error")
Degraded ("Degraded")
Unknown ("Unknown")
Pred Fail ("Pred Fail")
Starting ("Starting")
Stopping ("Stopping")
Service ("Service")
Stressed ("Stressed")
NonRecover ("NonRecover")
No Contact ("No Contact")
Lost Comm ("Lost Comm")
UserModeTime
-
Data type: uint64
-
Access type: Read-only
-
Qualifiers: Units ("milliseconds")
Time, in user mode, in 100 nanosecond units. If this information is not available, a value of 0 (zero) should be used.
For more information about using uint64 values in scripts, see Scripting in WMI.
Remarks
The CIM_Thread class is derived from CIM_LogicalElement.
WMI does not implement this class. For WMI classes derived from CIM_Thread, see Win32 Classes.
This documentation is derived from the CIM class descriptions published by the DMTF. Microsoft may have made changes to correct minor errors, conform to Microsoft SDK documentation standards, or provide more information.
