Yes it will be another challenge for hackers, but I think this one will be the most difficult because of the way it runs. There are so many checkpoints you have to go through, bypassing them would take an eternity. I don't know. Maybe I'm underestimating hackers. Wasn't XP supposed to be unlicensed-software proof? That didn't work out so well..... They'll have to rename "PC" because with this new OS it's not much of a "personal computer" anymore.
