There are various methods for checking authenticity. One would be to send
packets with machine identifiers behind your back. Intel are incorporating
Windows-specific designs that aid DRM and encryption that is dependent on
hardware. In turn, this implies that the means for duplication checks are
available. Spying cannot be disabled either as you have no access to the
source code. Although Windows runs in a confined box (VMWare), it remains
fully functional and behaves in quite the same way. It also has access to
the hardware, of course.
