This kinda statement is what makes folks blow off posts!. it is in fact. DEP is hardware enabled!. Maybe the first use of the palidan chip that is onboard the Microprocessor. this is in fact is a foot in the door to what will be coming soon as in when Microsoft first made the the announcement of longhorn. Which indeed caused an out roar they have since renamed and renamed palidan till the came up with DEP.
zdnet or maybe it was cnet reported silient updates are occuring again. the ones they did find seemed to be patches to fix a update. But then again blach Helios and stuff to pacify the crowd.
