I looked up a TPM for my Win10 desktop and one review said the Win11 checker still didn't like it. It also has a 6th gen cpu which I think is too old. Seems more likely that using one of the solutions to bypass the checks would work if I want to upgrade.

I have an Intel NUC from 2018. It has tpm 2.0, 16gb of ram but a cpu deemed too old. It’s faster than my sisters surface 2 laptop that I just upgraded for her that was released in the same year. I guess some cpus are more equal than others. The amount of e-waste from this blockage is going to be incredible.
