Accordingly, Redmond, Intel, Qualcomm and AMD have occupied the same room without injury long enough to promise that future products like Kaby Lake (Intel), 8996 (Qualcomm) and Bristol Ridge (AMD) will not be sullied with Windows 7 or 8.1 code.
Windows 7 is already getting put on a nil-by-mouth diet: it gets “security, reliability, and compatibility” support for older silicon until January 2020 (2023 for 8.1).
After 2017, Microsoft's post states, security fixes will only be released if they don't pose a risk “reliability or compatibility”.
The Terry Myerson-authored blog post says for Windows 7 to function, “device drivers and firmware need to emulate Window's 7's expectations for interrupt processing, bus support, and power states.
“As partners make customisations to legacy device drivers, services, and firmware settings, customers are likely to see regressions with Windows 7 ongoing servicing” (we suspect the post could have withstood more rigorous editing).
