As I wrote before, Intel small business marketing blogged in January 2016: "You might be resisting [migrating to Windows 10] because you're worried Windows 10 won't work with older computers. But rest easy, it's backwards compatible, meaning it's designed to work with older and newer computers alike. Upgrading your hardware can be expensive, so start with a free operating system update."
This was wrong at the time and remains wrong because Intel made a corporate decision to not support any processor graphics released before 3rd Generation Core (Ivy Bridge). Actually, Intel does not even include support for 3rd Generation Core processors on its most recent support post. Intel made this decision even though all of its former competitors in the motherboard business have released device drivers for many of their motherboards, while Intel washed its hands of the whole affair and left the motherboard business.
Recently the aforementioned blog entry was deleted, but I had taken screenshots of it.
