Note

If you're looking for info on pre-defined values to use for the Class and ClassGuid entries in the Version Section of the driver's INF file, see System-Defined Device Setup Classes Available to Vendors.

The following classes and GUIDs should not be used to install devices (or drivers) on Windows 2000 or later versions of Windows:

This class is reserved for system use.

Computer
Class = Computer
ClassGuid = {4d36e966-e325-11ce-bfc1-08002be10318}
This class is reserved for system use.

Decoders
Class = Decoder

ClassGuid = {c459df55-db08-11d1-b009-00a0c9081ff6}
This class is reserved for system use.

No driver
Class = NoDriver
ClassGuid = {4d36e976-e325-11ce-bfc1-08002be10318}

This class is reserved for system use.

Other Devices
Class = Unknown
ClassGuid = {4d36e97e-e325-11ce-bfc1-08002be10318}
This class is reserved for system use. Enumerated devices for which the system cannot determine the type are installed under this class. Do not use this class if you are unsure in which class your device belongs. Either determine the correct device setup class or create a new class.

Printer Upgrade
Class = PrinterUpgrade
ClassGuid = {4d36e97a-e325-11ce-bfc1-08002be10318}
This class is reserved for system use.

Print Queue
Class = PrintQueue

Software Device
Class = SoftwareDevice
ClassGuid = {62f9c741-b25a-46ce-b54c-9bccce08b6f2}

USB Bus Devices (hubs and host controllers)
Class = USB
ClassGuid = {36fc9e60-c465-11cf-8056-444553540000}
This class includes USB host controllers and USB hubs, but not USB peripherals. Drivers for this class are system-supplied. Drivers for USB peripherals should use the appropriate class from System-Defined Device Setup Classes Available to Vendors that matches the functionality of the peripheral, or use the USBDevice class if no other class is a better fit.
