Globally Unique Identifier, a unique 128-bit number used in a windows registry to identify COM DLL. Lot of COM object information is known by identifying the registry and the correct GUID. Windows also identifies the user accounts by a user name and assigns it a GUID. GUIDS are also used by database administrators as primary key values in the databases.
