Q: I read an article this week headlined: "The latest Kaby Lake,
Zen chips will support only Windows 10." It claimed Intel and
AMD's new processors are "officially supported only by
Microsoft’s Windows 10." This can't be true? What about Linux?

A:  The short answer is Intel's Kaby Lake aka its
seventh-generation Core i3, i5 and i7 processors, and AMD's
Zen-based chips, are not locked down to Windows 10: they'll boot
Linux, the BSDs, Chrome OS, home-brew kernels, OS X, whatever
software supports them.

So if you want to use Linux or some other non-Windows OS on your
new CPUs, you'll be fine. It's OK, we checked.

Q: Sweet. What about Windows 7? Or Windows 8.1? Or any Windows
pre-10?

A:  Yeah... nah. Shad Larsen, Microsoft's director of Windows
business planning, blogged earlier this month:

"Future silicon platforms including Intel's upcoming 7th Gen
Intel Core (Kaby Lake) processor family and AMD’s 7th generation
processors (e.g. Bristol Ridge) will only be supported on Windows
10, and all future silicon releases will require the latest
release of Windows 10."

Given that there are still millions of XP holdouts even today,
the likelihood of everyone simply falling into line and paying a
$10 -- $25 monthly fee per seat because Micro$oft say they must
seems very small to me.  My sense is that all but the Windows
fanboyz and the really big corporations will say "buggrit" and
move to Linux, faute de mieux.  Unless we offer a choice.
