Yes, you can upgrade the TPM 1.2 firmware to 2.0, but none of the processors supported in the 800 G2 SFF model series meet Microsoft's minimum W11 hardware requirements.

See this link for how to update the TPM firmware to 2.0.

You want this file for the 800 G2:

https://ftp.hp.com/pub/softpaq/sp87501-88000/sp87753.exe

I have attached the instructions to run the update below:

They can also be found in the folder that will be created when you run sp87753.

Regarding the installation of W11 on your PC:

You can install W11 on your PC, but you would have to use a workaround to do so.

If you are happy with your PC, and if you are interested in installing W11 24H2 on your PC as is, watch this video, which is the easiest way to do it in my opinion, and I have tried many different ways to do this during the last 3 years.

Download the W24H2 ISO file and use that (3rd option).

Download Windows 11

You can download the free 7-Zip file utility from the link below. The top line is for 64 bit.

You'll have to repeat this procedure each October when Microsoft rolls out the new builds because a PC that does not meet Microsoft's minimum W11 hardware requirements will never automatically get the update to the next build.

Other than that, your PC will continue to get the monthly cumulative and other updates.

That's only a minor inconvenience to have continued OS support beyond October of 2025.

If things don't work right on W11, you have 10 days to easily go back to W10 as long as you don't delete the W1 upgrade files or the Windows.old folder.
