>After 4 years they'll either not get security updates or have to switch to Linux. To be fair, Windows 10 will be 10 years old at that time and their PC will be over 11 years old which is an eternity in technology time. 11 year old HW is not very energy efficient and is often vulnerable to various side channel attacks that need SW mitigations which make them even slower. Newer HW is more secure, while being more energy efficient to boot. Even if Microsoft would continue support for ancient hardware, the chances are Nvidia and AMD would drop driver support for what they consider to be legacy hardware, like they alwasy do.
I also keep my 15 year old PC (Core 2 Quad) going for my parents but I moved it to Linux as I can't expect Microsoft to keep supporting such old hardware for free forever and at some point, the SW and HW industry have to keep moving forward and that sometimes means removing support for legacy stuff even if that means cutting some users with old hardware off (they still can keep using their systems after all, just not run the latest and greatest SW).
Is Apple doing better officially supporting hardware overs 10 years old?
