According to Microsoft,
A CLSID is a globally unique identifier that identifies a COM class object. If your server or container allows linking to its embedded objects, then you need to register a CLSID for each supported class of objects. The CLSID is stored under the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID = <CLSID>The CLSID value specifies a name that can be displayed in the user interface. The CLSID value contains information used by the default COM handler to return information about a class when it is in the running state. To obtain a CLSID for your application, you can use CoCreateGuid. The CLSID is a 128-bit number, spelled in hexadecimal format, within a pair of braces.
From the Windows Run dialog, you can launch a location using a CLSID by prefixing it with shell:::. For instance, to open the Control Panel on Windows 7, enter the following:
shell:::{21EC2020-3AEA-1069-A2DD-08002B30309D}
To do this from the command prompt, you have to add explorer before it (to run from explorer):
explorer shell:::{21EC2020-3AEA-1069-A2DD-08002B30309D}
