Vista - Anyone yet discovered a solution to the Vista scheduler problem?

Anyone yet discovered a solution to the Vista scheduler problem - being that
if ever you log out or reboot (and login again), the scheduler 'forgets' the
user privileges & so any/all attempts to resume the schedule fail, fail,
fail, fail, grrrrrrrrrrrrrrrrrr

This was documented when Vista first appeared & reported solution was just
keep resetting the user every time - but it sorta defeats the object of an
otherwise automated scheduled task

I have tried setting the user as 'system' (as per defrag task, etc) but
that doesn't work either
