I remember some people reporting that their old PCs with unsupported CPUs got a high CPU usage after installing Windows 11, and I remember some people saying that it was because they lacked TPM, which increased the CPU load. But it turned out to be just a bug, didn’t it? After all, features like memory randomization that require TPM couldn’t be enabled on Windows 11 anyway, and similar CPU usage spikes were seen on Windows 10 as well.
