   This function returns a 64-bit value that is numerically larger then the last
   time the function was called.

+  The platform monotonic counter is comprised of two parts: the high 32 bits
   and the low 32 bits. The low 32-bit value is volatile and is reset to zero on
   every system reset. It is increased by 1 on every call to GetNextMonotonicCount().
   The high 32-bit value is nonvolatile and is increased by one on whenever the
