Want to install windows 11, but the problem is we have TPM 1.2 firmware version available

You can update the TPM firmware to 2.0 but your notebook's processor still won't meet Microsoft's minimum W11 processor requirements of an Intel 8th gen or newer one.

 

For that, you would need an Elitebook 840 G5.

 

See this link for how to update the TPM firmware:

 

HP Desktops, Notebooks, and Workstations - HP TPM Configuration Utility With Windows 10 Anniversary ...

 

You can install W11 without having to update the TPM firmware to 2.0.

 

If you are interested in installing W11 on your PC as is, you can read this discussion for how I upgraded several (more than 10) HP and Dell notebook and desktop PC's that did not meet the W11 hardware requirements to W11 22H2/22H3.

 

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.
