Microsoft said that as new silicon generations are introduced, they need the latest Windows platform for support. This will allow Microsoft to focus on deep integration between Windows and the silicon, while maintaining maximum reliability and compatibility with previous generations of platform and silicon. “We are committed to working with Microsoft and our ecosystem partners to help ensure a smooth transition given these changes to Microsoft’s Windows support policy”, and Intel clarified: "No, Intel will not be updating Win 7/8 drivers for 7th Gen Intel Core [Kaby Lake] per Microsoft's support policy change."
An AMD representative was equally neutral. “AMD’s processor roadmap is fully aligned with Microsoft’s software strategy,” AMD chief technical officer Mark Papermaster said, via a company spokeswoman.
