ZDNet has word that Microsoft has figured out another way to strong-arm users into adopting Windows 10, saying some upcoming new CPUs will require Windows 10 (or, you know, Linux). Microsoft explains the move in this blog post which says this shows they are embracing "silicon innovation" (thanks HARDOCP). Harming their contention that this is necessary is word that certain CPUs will be allowed a grace period to run older versions of their operating system:

• Going forward, as new silicon generations are introduced, they will require the latest Windows platform at that time for support. This enables us to focus on deep integration between Windows and the silicon, while maintaining maximum reliability and compatibility with previous generations of platform and silicon. For example, Windows 10 will be the only supported Windows platform on Intel’s upcoming “Kaby Lake” silicon, Qualcomm’s upcoming “8996” silicon, and AMD’s upcoming “Bristol Ridge” silicon.
• Through July 17, 2017, Skylake devices on the supported list will also be supported with Windows 7 and 8.1. During the 18-month support period, these systems should be upgraded to Windows 10 to continue receiving support after the period ends. After July 2017, the most critical Windows 7 and Windows 8.1 security updates will be addressed for these configurations, and will be released if the update does not risk the reliability or compatibility of the Windows 7/8.1 platform on other devices.
