Disabled CPU autoselect itself when starting rendering

[cadman5]

I got a dual xeon E5 2690 v4 workstation running windows 7 enterprise edition at work and when tried to exclude one CPU from 3dsmax (Through task manager/processor affinity) it will get re-selected when I start rendering. Any ideas?
