Win32_SystemConfigurationChangeEvent - The Win32_SystemConfigurationChangeEvent is an event class which indicates that the device list on the system has been refreshed. Refreshed meaning: a device has been added, removed, or the configuration changed. This event is fired when the windows message 'DevMgrRefreshOn<ComputerName>' is sent. The exact change to the device list is not contained in the message and therefore a device refresh is required in order to obtain the current system settings. Examples of configuration changes affected are IRQ settings, COM ports and BIOS version, to name a few.
