Outside of device driver programming, knowing the globally unique identifier (GUID) for a hardware device class is useful when tracking down driver information in the Windows Registry.

For example, the solution to several Device Manager error codes includes removing specific registry values from registry keys named after a device's GUID.

This is not an exhaustive list, and not all Windows versions use every GUID in this table. Several less common system-defined device classes exist. Also, devices can generate unique classes based on variables, which makes it impossible to list them all.

What Are GUIDs?

A globally unique identifier (GUID) is just that: a unique number used, in this context, to identify specific hardware components. Windows creates the GUID, written in hex as a 128-bit alphanumeric string, for each piece of hardware. A GUID starts with one set of eight hexadecimal digits, followed by three groups of four digits and then one group of 12 digits.
