Intel Kaby Lake and AMD Zen processors to only support Windows 10 and Unix
News hits the web on multiple websites today that it seems likely that both AMD ZEN and Intel's Kaby lake processors are to only support Windows 10 and Unix compatible operating systems. That would be bad news for the guys still on Windows 7 looking forward to an upgrade.
The news hits the web today through PC Gamer. Microsoft already announced this news earlier this year, but we didn't know about ZEN on this one. It makes sense though but yes, Microsoft is planning to only support the new processors on Windows 10 (so this is not an AMD or Intel thing). Basically Microsoft will not support the new processors on older operating systems. While I do believe the standard instruction sets should be supported, the niche multi-media functions etc thus should not be. So it remains to be seen how compatible these processors are going to be.
"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," Microsoft stated in a blog post earlier this year.
"As new silicon generations are introduced, they will require the latest Windows platform at that time for support,” a Microsoft spokeswoman stated. "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."
So, what happens if you install a Kaby Lake processor in a desktop PC running Windows 7? Good question—nobody knows outside of Microsoft and Intel, and until the CPUs are out in the wild, no one will have the opportunity to try it out. One unnamed source told PCWorld that without support and security updates, his guess is that the experience would be "a bit glitchy." Another surmised that certain apps trying to use features built into the chips could crash. Even if you can get the OS installed, it would likely be a sub-optimal experience at best.
There's not a whole lot Intel and AMD are saying about this. Both chipmakers provided canned responses when asked for thoughts on the subject, with Intel confirming it has no plans on updating Windows 7 and Windows 8/8.1 drivers for Kaby Lake "per Microsoft's support policy change."
Obviously everything not Microsoft will support the processors like *nix distributions such as ChromeOS, SteamOS, and OS X.

Just because it is not officially "supported" doesn't mean windows 7 won't work, just won't be able to complain if you have problems. Just a clever way to trick everyone into buying new windows 10 licenses.

I can see the CPU work, but simply not optimized for the OS ? In more advanced stages you could see similarities with Windows XP, for example ever since I think it was Haswell, Windows XP simply refused to install on that processor.
But I do think it'll work, but comparable to older graphics card, an an optimized legacy status. Not sure though, time tell.

Good, i find this as a positive notion. This will allow to get maximum optimization for latest system and provide ease for both developers of OS and Software to optimise it in order to make it work optimally, instead of wasting resources trying to make it compatible.
Windows 7 is old and dated, besides using it for work on some older application / machine GUI's e.t.c. that were not updated for YEARS (same as some companies using Win 95/ 98/ ME/ XP, for that same purpose) there is absolutely 0 reasons for not moving to New OS - Win X in our case.
While i personally probably wont upgrade to 7700k processor, and rather wait for next 10nm generation, a lot of people will upgrade, and i see this as a great benefit for them!

I agree. It's likely that Windows 7 and 8.1 could still work with the new processors, you just won't be able to use any of the new instructions. However, the CPU will probably not be recognised by the OS either, seeing as Windows does load CPU 'drivers' which mostly relate to microcode etc. Look under device manager, processors, you will see that for Intel (example) that there is intelppm.sys for Intel CPU's, and amdk8.sys or amdppm.sys for AMD processors.
If you run Windows 7 or 8.1 with Kaby Lake or Zen, it will likely just mean you will see a yellow exclamation mark in the device manager. I'm not sure what happens in this case, quite possibly you won't have access to anything but the base required extensions? If they did add support for these devices, as long as the new instructions don't affect registers then it will be possible. I don't believe any of the new instructions on Kaby Lake or Zen require a new kernel like was required with AVX, neither support AVX-512 from what I know of (that will be added later to the standard CPU's).
In any case, even if they did add 'support' for it on Windows 7 and 8.1, they won't go to the extent of adding support for other new features of the CPU and motherboard. They gain nothing doing so, and support for Windows 7 and 8.1 has been pretty good considering almost any other company would have dropped support from them pretty much straight after a new version comes out apart from security updates.
Well not a big problem really, old cpu-s support windows<10 so not a big deal anyone who wants new cpu will use win 10 and newest mobos

HOW does a CPU NOT support an older operating system, it just carries out a bunch of instructions?
