The Device Manager is loaded by the kernel, it runs continuously, and it manages loaded device drivers and their interfaces. When the Device Manager loads, it also loads the I/O Resource Manager to read a list of available resources from the registry.

The Device Manager tracks interfaces advertised by drivers and supports searches for drivers based on a globally unique identifier (GUID). The IClass interface can associate an interface GUID with the driver's legacy name, its $device name, or its $bus name. For example, COM1:, $device\com1, or $bus\pci_0_3_0.
