If you upgrade to Windows 11 on an unsupported PC, you will have to sign a waiver first

While we now know that Microsoft will only provide support for the new OS to the processors from both Intel and AMD that are in its list of supported CPUs, the company also stated that users on unsupported systems could still go ahead with an install using ISOs if they are interested. But this in return would leave their systems in an unsupported state.

It has been reported that this unsupported state may even mean that such PCs won't also receive critical security updates. So when a user does want to upgrade to Windows 11 from such existing systems, the following formal agreement, or something similar, would be popping up.

The notice basically states that installing Windows 11 on such PCs is not recommended", and that they are not entitled to updates". I could muster up some respect for Microsoft if their cut-off was a hard cut, but this wishy-washy situation is terrible for consumers.
