Using the Parallel For Loop, such as photos

The CPU Information.vi to enter the eight core to Parallel For Loop
I open the Task Manager, but looks like only four core operation
And the utilization rate of only 10%

I want this computer 8 core continue to run this Loop
 
what's  wrong ? (CPU for I7-3770)

Hi,

you're using an ExpressVI. Maybe this one is blocking resources and forces the loop to run on just one core?
