A recently published Knowledge Base article suggests that Microsoft is going to block Windows Updates for owners of the latest Intel and AMD processors if they try to run Windows 7 or 8.1.
Last year, Microsoft announced a shift in the way it would support Windows. Going forward, new processors, including Intel’s Kaby Lake and AMD’s recently-released Ryzen, would require the newest version of Windows. Users of Windows 7 and 8.1 would be out of luck, with Microsoft having no plans to support the new chips on the old operating systems.
Skylake was originally going to be included in this policy, too, but Microsoft partially relented, switching instead to a policy of providing only security fixes for Skylake systems running Windows 7 and 8.1.
