I have a perfectly good PC from 2015 that has a Gen 5 Intel processor. It is 64-bit, 6-core, supports TPM 2.0, and supports the virtualization instructions, UEFI, etc.
I have 64 gigs of ram in this and other upgrades, it works great, but it will die with Win 10 because the CPU isn't on Microsoft's list. When Win 10 support is done, so is my PC that I've invested a lot of money in. So yeah, it's going to become trash or a Linux box I haven't a need for.
Why do you think that there will be actual checks for this list. This is just a list intended for OEMs that build new machines. NO WAY there will be cpuid checks to exclude your processor specifically.
Given a few years of time passing, generally motherboard upgrades require changing the physical format of the CPU and RAM interfaces, which means everything's wasted.
