Yes, Windows 7 (currently in the Extended support phase) will continue to receive updates until January 14, 2020, and Windows 8.1 will be supported until January 10, 2023. But in a series of "clarifications" to its support policy today, the company announced that support for those older Windows versions will be available only for "previous generations of silicon."Going forward, as new silicon generations are introduced, they will require the latest Windows platform at that time for support... 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.
The policy will be phased in beginning with systems based on Intel's new 6th-generation CPUs (code-named Skylake), which debuted a few months ago. New consumer-based Skylake devices must run Windows 10 to be supported.
Good way to force Windows 10 usage.
Edit: I wonder if Microsoft will refuse to activate previous OS's on the new hardware.
