Many people run pirated copies of Windows and Office . I think that if people start to have to actually pay for MS software, they might quickly start looking for alternatives and thus unlocked hardware. That's been the hope for quite some time, and it might finally come true.
What is more, I wonder how having a 'secure boot' will prevent Windows system from being infected by viruses.
Also, from what I can see on forums, people do as they are told, even if you tell them to run 'sudo rm -rf /'
This leads me to think that many people might actually "turn off security" on their machines:
* not to pay for Windows
* not seeing any benefit
* not understanding what they are doing and proceeding as instructed on a forum or wiki
