Please check to see is your machine in there.

• If Yes, you can upgrade your machine.
• If No, sorry.

Hi, @chuckinalong11 

Even if you could upgrade the TPM 1.2 firmware to 2.0, your PC still doesn't meet Microsoft's minimum W11 processor requirements and no upgrades are possible.

Windows processor requirements Windows 11 supported Intel processors | Microsoft Learn

If you are interested in installing W11 on your PC as is, you can read this discussion for how I upgraded several HP and Dell notebook and desktop PC's that did not meet the W11 hardware requirements to W11 22H2.

You have to use the version of the Rufus utility that I zipped up and attached in the discussion (v3.18).

If the in-place upgrade fails, you should be able to clean install W11 using the bootable W11 installation flash drive you made with Rufus.
