TPM version?

[Jpx1]

Hello,
I have a Phoenix h9-1210ef i5-3450 64-bit W10 8GB RAM 1.8TB HDD tower PC (purchased in 2013!!! Very happy with it, great hardware!!! And I'd like to keep it if possible by upgrading it..?:-)) ) but it tells me it won't be able to upgrade to W11, even though I have the necessary memory and disk space resources. But

1) Regarding the TPM, I can't see which version I have.
I typed "tpm.msc" but it says "compatible Trusted Platform Module not found." If I understand correctly, it must be 2.0 to upgrade to W11.
I accessed the BIOS but I don't see this information.

2) There are tools to bypass this security so that Windows 11 can install on "old" PCs like mine, but what do you think? What are the risks?
Thanks for your advice! 🙂

Hi:

Your PC does not have a TPM security device and even if it did, the i5-3450 processor it has falls 5 Intel processor generations short of meeting Microsoft's minimum processor requirements to run W11.

You can still upgrade to W11 without an Intel 8th gen core processor or a TPM security device, but you have to use a workaround to do so that bypasses the W11 hardware checks.

If you are interested in installing W11 24H2 via an in-place upgrade 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 or a similar 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.
