Is there a practical difference? I.e, what does fully supported mean? For context, I had assumed an older laptop was unable to upgrade until I tried it, then did some research. Wondering if I missed something subtle.
It means that Microsoft won't suddenly disable your Windows 11 install's ability to update. Microsoft has already, on at least one occasion, disabled further updates for computers that don't meet their specified requirements in regards to processor and TPM.
A lot of the users of 10 we're talking about wouldn't know how to get Windows 11 working again after updates were stripped again.
