Another is for the user to disable the PSN feature each time the computer boots up. This can be done through the Windows registry via a utility in the Start menu, and the user will be notified by an icon that the feature is disabled. Finally, Intel is providing information to computer manufacturers and BIOS makers on ways to mask the PSN in setup mode, before the PC is even shipped to a customer. That way, you and I can request a PSN-disabled PC at purchase time. None of these methods is totally foolproof.
Hackers can figure out a way to access anything involving software.
Until that happens, users need to decide for themselves whether they can live with the feature. Intel is to be credited for handling the PSN controversy far better than the math flaw it had with the original Pentium. The company has been open about its reasons for implementing the feature. Intel has made clear that it will not try to track PSNs.
