Win32_SystemConfigurationChangeEvent class

Article
01/06/2021

The Win32_SystemConfigurationChangeEvent WMI class indicates that the device list on the system has been refreshed (a device has been added or removed, or the configuration changed). An event is fired and an instance of this is class created when the "DevMgrRefreshOn<ComputerName>" message is sent. The exact change to the device list is not contained in the message, so a device refresh is required to obtain the current system settings. Examples of configuration changes affected are IRQ settings, COM ports, and BIOS versions.

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

Properties

Properties

The Win32_SystemConfigurationChangeEvent 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.

This property is inherited from Win32_DeviceChangeEvent.

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_SystemConfigurationChangeEvent class is derived from Win32_DeviceChangeEvent.
