Resistant means that it would not be able to be pirated, thats why MS had the activation procedure, but people found a way to get around that. M$ shot themselves in the foot when they where demoing it. They demo'd it to compnies that said they can not demo it if it requires activation to work. I read about that. Beta testers shared the ISO'z and such. Did you know you can install win98 w/o a serial?? You can install almost ANY M$ product w/o the serial. I have access to the beta site(cuz I did some beta testing) and they got programs/workarounds on how to have it by-pass the serial for like OEM licenses.
