It’s not working because W11 is using a CPU instruction that doesn’t exist in older processors.

And by older, I don’t mean Pre-Zen or Intel 5XXX… I mean OG AMD Athlon and Intel Core 2 Duo. If you’re trying to run on a CPU from 2008, that’s on you. These were never supported - hence the title.

The only reason this was discovered was because some YTers make videos of running W10/11 on super old computers.
