Windows 11 requires TPM 2.0 and my computer currently has TPM 1.2

Since Windows 11 requires TPM 2.0 and my computer currently has TPM 1.2, I'll need to check if my system supports upgrading to TPM 2.0.

Your PC also requires an Intel 8th generation core processor, to meet Microsoft's minimum W11 Intel processor requirements, so even if you could update the TPM 1.2 firmware to 2.0 (which you can't), the PC still falls short.

Only the PC's on the list at the link below support a firmware upgrade from 1.2 to 2.0:

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.

I'm running W11 24H2 on my year older HP 8200 Elite CMT and it works fine.

Hey,
Thanks for this thread and it's also helpful for me too

You're right, Windows 11 requires TPM 2.0, and the HP Compaq Pro 6300 Microtower typically comes with TPM 1.2. Unfortunately, this model doesn't support upgrading to TPM 2.0, as the TPM chip is soldered onto the motherboard and not user-upgradable. You can still run Windows 10 without any issues, but upgrading to Windows 11 officially on this hardware isn't supported unless you bypass the TPM check (not recommended for most users). Hope that helps!
