Win32_DeviceChangeEvent class
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
class Win32_DeviceChangeEvent : __ExtrinsicEvent
{
uint16 EventType;
uint8 SECURITY_DESCRIPTOR[];
uint64 TIME_CREATED;
};
