A LUID (locally unique identifier) is a 64-bit value guaranteed to be unique only on the system on which it was generated. The uniqueness of a LUID is guaranteed only until the system is restarted.
A LUID is not for direct manipulation. Drivers must use support routines and structures to manipulate LUID values.
LowPartLow order bits.
HighPartHigh order bits.
The LUID structure is an opaque structure that specifies an identifier that is guaranteed to be unique on the local machine. For more information, see the reference page for LUID in the Microsoft Windows SDK documentation.
