Using GUIDs in Drivers
Drivers and other system components use globally unique identifiers (GUIDs) to identify a variety of items. System components define GUIDs for items such as device setup classes, PnP events, WMI events, and still image events. Driver writers can create GUIDs for items such as device interface classes, custom PnP events, and custom WMI events. Drivers and applications include header files that define the GUIDs that they use.
