“Support for Windows 7 and 8.1 on certain Skylake PCs will now continue until July 17, 2018, a one-year extension from the original deadline. After that date, Microsoft and its computer-making partners will not guarantee that they will revise device drivers to support those editions of Windows on newer hardware.” – Computerworld
They’ve also retreated regarding critical security updates: They will receive ALL updates through their January 2020 and January 2023 retirement dates. This was driven by user complaints they received over their January 2016 change regarding Skylake equipped computers, as well as Lenovo’s negative feedback to MS regarding their ill-advised policy.
“Some parts of Microsoft's revamped Windows 7 and 8.1 support policies did not change today: Microsoft still expects customers to upgrade their Skylake PCs Windows 10 by the new deadline, and the declaration that post-Skylake silicon will support only Windows 10 remained intact.” – ibid
So, for the most part, good news for W7 and W8.1 users who aren’t surprised by installation of W10 when they aren’t looking.
