Win32_DeviceChangeEvent class

Article
01/06/2021

The Win32_DeviceChangeEvent abstract WMI class represents device change events that result from the addition, removal, or modification of devices on the computer system. This includes changes in the hardware configuration (docking and undocking), the hardware state, or newly mapped devices (mapping of a network drive). For example, a device has changed when a WM_DEVICECHANGE message is sent.

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

Syntax

Properties

Properties

The Win32_DeviceChangeEvent class has these properties.

EventType

Data type: uint16
Access type: Read-only
Qualifiers: MappingStrings ("Win32APIDevice Management Messages|WM_DEVICECHANGE|wParam", "Win32APIDevice Management Messages|WM_SETTINGCHANGE")

Type of event change notification that has occurred.

Configuration Changed (1)

Device Arrival (2)

Device Removal (3)

Docking (4)

SECURITY_DESCRIPTOR

Data type: uint8 array
Access type: Read-only

Descriptor used by the event provider to determine which users can receive the event. This property is inherited from __Event. For more information about constants used to set this security descriptor, see WMI Security Constants.

TIME_CREATED

Data type: uint64
Access type: Read-only

Unique value that indicates the time at which the event was generated. This is a 64-bit value that represents the number of 100-nanosecond intervals after January 1, 1601. The information is in the Coordinated Universal Times (UTC) format.

This property is inherited from __Event.

For more information about using uint64 values in scripts, see Scripting in WMI.

Remarks

The Win32_DeviceChangeEvent is an abstract class derived from __ExtrinsicEvent.
