The locally unique identifier (LUID) is a 64-bit value guaranteed to be unique on the system on which it was generated only. The uniqueness of an LUID is guaranteed until the system is restarted only.

A LUID is not designed to be manipulated directly. Drivers must use support routines and structures to manipulate LUID values.
