Hello,

How to upgrade TPM 1.2 to 2.0 for HP ZBOOK 15 G2? Is it possible?

It's needed for upgrading to Windows 11.

Thanks

Hi:

Your notebook is not on the list at the link below that can support an upgrade from TPM 1.2 to 2.0.

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

Also, even if your notebook had a TPM 2.0 security device, none of the processors supported in the model series meet Microsoft's minimum W11 processor requirements of an Intel 8th generation core or newer processor.

If you are happy with your PC, and if you are interested in doing an in-place upgrade from W10 > 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.

How to Install Windows 11 on Unsupported PC in 2025 (New Easiest Method, No CMD)

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.

7-Zip

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.
