Hi:

You also can't upgrade to W11 because none of the processors supported in your PC meet Microsoft's W11 hardware requirements.

The list of supported processors can be found in chapter 2 on page 6 of your PC's service manual.

Windows processor requirements Windows 11 supported AMD processors | Microsoft Learn

So, even if your PC had a TPM 2.0 security device, the processor won't be supported.

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.
