> my CPU (which is supported) isn't supported

Could it be that TPM is disabled in the bios? Could just be that the machine has all the supported hardware, just that the hardware is inaccessable in software.

There are ways to bypass the TPM and Secureboot checks and install 11 even on unsupported CPUs / lack of TPMs (Saying its an i7 so it should be supported doesn't help because the first i7 was release in 2008 iirc) by using things like https://github.com/AveYo/MediaCreationTool.bat to skip windows 11 upgrade checks. You just don't get support for the features requiring TPM/secure boot and no guarantees that things won't break in the future.

I do not believe the migration tool checks the class/Intel brand of CPU (i3, i5, i7, i9) but the generation, which seems to be 10th gen and higher. You can search this list to see if your generation of Intel processor is supported.

That doesn't tell anyone much.

The first i7 was released in 2008.

Fair although my one is like 3 years old. Anyhow it's moot as my PC has recently caught a bout of "can't stay on for long enough to boot" and I haven't got around to fixing it yet.
