> But this article could be written at any time, with any version of Windows
Completely wrong. Previously you always could install the newer Windows. It might be slow, but it'd work. Microsoft has now gone out of their way to specifically forbid installing Windows 11 on old hardware so they can enforce DRM.
The only reason for any of this is because someone managed to convince microsoft that they should only support hardware with a modern TPM which the typical user will not benefit from. Instead it benefits those who wish to push DRM and "trusted computing", which is not the end user.
