Important to note:
Microsoft’s official system requirements for Windows 11 already included an eight-generation Intel Core CPU or later, or a second-generation Ryzen processor or later, as well as other PC features like TPM 2.0. This change only affects people who bypassed those official requirements on computers with incredibly old processors. If you have a PC just outside of the official requirements, such as a first-gen Ryzen laptop or a desktop with a seventh-generation Intel CPU, you’re still fine for now.
So... Windows 11 Has Stopped Working on Older CPUs... IF LIMITS ARE INTENTIONALLY BYPASSED AND YOU INSTALLED ON UNSUPPORTED HARDWARE
This isn't something where Microsoft changed the minimum requirements and the average Joe is no longer able to use their computer.
