My computer, despite being bought in 2016, and having a processor released in 2015, doesn't support this**.
So I guess I'll be stuck on Windows 10 for the forseeable. At least the minimum requirements for Windows 10 were basically the same as for Windows 7***
I guess that by the time Windows 10 goes out of support (October 2025) I'll have had this PC for a decade. But it works well, runs every game I want to play, and it feel very wrong to obsolete it because MS put in a requirement for some technology that they could totally run without if they wanted to.****
Ah well, hopefully something will change in the next 4 years!

*** 1Ghz processor, 1GB RAM, not that I'd want to run either OS in that little RAM.
****They could even check your motherboard/CPU was recent enough to support it, and insist you turned it on if so.
