When my limited users shut down they receive a memory write error from the McAfee service! This problem was also present in the 2007 edition of McAfee Security Center. And, hasn't been present in the later versions -- until now!
Copy and paste programmers at work!
And, because I'm not technically a new customer I get no direct response from McAfee (as I did in 2007).
So, does anyone have a clue how to correct this memory write problem, other than allowing all users administrator access?!
