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. See my Complete List of Device Manager Error Codes for more on those types of errors.

Note: This is not a complete list of device class GUIDs. Several less common system defined device classes exist. Also, devices can generate unique classes based on various variables making it impossible to list them all.
