GUID Explorer 1.0.005

As an in-house test and development tool, we developed a utility that allowed us to explore the device details for a particular GUID. This utility may be useful to other developers so we are making it available as a free download.

What does the utility do?
Windows 2000/XP/Vista provides a set of APIs that allow a developer to enumerate a particular device class GUID, and determine additional information on each device that is detected.

We display the GUID identifier string as theyre declared in the Windows 2000 DDK header file. Select the GUID that interests you. This will show you the enumerated device objects that the OS returns. You can then select a device and a device property youd like to view. The device property will appear in hex and ASCII in the bottom portion of the dialog box.

The APIs we use are part of the SetupDiXxx class of APIs as described in the Windows 2000 DDK. Please refer to the DDK for additional information on this application. Youll want to pay particular attention to the following APIs which we use:

SetupDiGetClassDevs()
SetupDiEnumDeviceInfo()
SetupDiGetDeviceRegistryProperty()
SetupDiDestroyDeviceInfoList()
What operating systems are supported?
This software is only designed for Windows 2000/XP/2003/Vista. It is also compatible with the x64 versions of Windows.

What does it look like?
Heres a sample screen shot for a Disk Drive class device. As you can see, the OS has detected three Disk Drive class devices on our test system.
