cpu hog I remeber stopped apps from overloading the proc and locking up Windows, if you want to enable all cores at Windows boot, do this, Start, Accessories, Run(right click, run as admin), type msconfig, hit enter, open the boot tab, Advanced options, in the next box, put a check in Number of Processors, select the number of cores that you want to use during boot, hit OK, in the next box Apply, when the box closes it will say that you need to restart the computer, pick now or later. good luck
