Yeah, that's exactly it. One extra tip: you can sometimes bypass it with a registry edit, but it's not officially supported and might cause issues later.

You could also check if your motherboard has a TPM 2.0 setting that needs to be manually enabled in the BIOS. Hope that helps.

Agreed. Ah, that Pentium G4560 is actually one of the CPUs that isn't on the official Windows 11 supported list, so that's likely the hard blocker.

I had the same problem with an older processor. The list of supported CPUs is really strict, and there's no official workaround for that specific error. Hope that helps.

This. You could also check if your motherboard supports TPM 2.0 and Secure Boot, as those are also required. Let me know if that works.

+1 I had the same problem with an older CPU. That Pentium isn't on Microsoft's supported list, so it's a hard block, even if TPM is enabled.

You could also look into a clean install using an ISO, as that sometimes bypasses the upgrade block for unsupported hardware. Let me know if that works.

I had the same problem with an older processor. The clean install trick the other user mentioned is what finally worked for me. Hope that helps.

Yeah, that Pentium G4560 is actually on the official unsupported CPU list, so the clean install might be your only real shot. Good luck!

Yeah, I had the same problem with an older CPU. I ended up just sticking with Windows 10 for that machine.
