Microsoft (in)famously requires that your PC have a special security chip (TPM) in order to install Windows 11. But the requirement is wholly unnecessary to maintain a secure installation. And it requires many people to buy new PCs, arguing that this is likely the primary reason Microsoft implemented the requirement.

Patching the Windows install to allow it to run on existing hardware without a TPM chip has been a game of cat and mouse. And until now it had again been thwarted by Microsoft.

Recently Microsoft has patched the Windows 11 ‘product server’ trick for TPM check bypass, but the bypass still works with setupprep.exe. This bypass will upgrade Windows 10 clients to Windows 11 without requiring a TPM.
