Windows Upgrade Help and more

Agreed. I had the same problem. I ended up having to update my BIOS to get TPM 2.0, even though my board technically supported it.

This. Yeah, that's exactly it—check your motherboard manufacturer's site for a BIOS update that enables TPM 2.0.

Also, you might need to specifically enable "Intel Platform Trust Technology" in the BIOS after updating.

Yeah, that's the issue—Windows 11 requires TPM 2.0, and your CPU only supports 1.2, so you'll need to check if a firmware update is even possible.

Agreed. You could also try a clean install using the official ISO and bypassing the TPM check, though that's not officially supported. Another option is just sticking with Windows 10, which is still getting security updates for a while.

Agreed. I had the same problem with my 6700K. I ended up using the registry bypass to install it, but honestly, it's been a bit buggy. Let me know if that works.

Same here. You could also check if a firmware update from your motherboard manufacturer enables TPM 2.0, as some older boards got support that way.

Yeah, and if that doesn't work, you might need to manually enable fTPM in your BIOS settings. Let me know if that works.

Agreed. You could also try using a registry edit to bypass the TPM check, though that's not officially supported. Another option is to just stick with Windows 10, which is still getting security updates for a while.

+1 Yeah, that registry edit is a common workaround, but have you double-checked in your BIOS to see if there's actually a setting to switch from TPM 1.2 to 2.0?
