It won't. The TPM is just a storage mechanism for keys. To me it looks that Windows 11 is an attempt to enforce a new hardware baseline. I don't think that their TPM requirement is artificial nor excessive, just that most people don't even know where it is in their bios and they panic. It's the same for UEFI/GPT, and to an extension for systems using pre-DX12 GPUs, non-NVMe drives, and CPUs without hardware mitigations. Windows 10 is perfectly fine for the next four and a half years. I'm worried that Microsoft is stupid and they will actually back off.
