Even if you upgrade the TPM 1.2 security chip to 2.0, the PC still doesn't meet Micrsoft's minimum W11 processor requirements of an Intel 8th gen core or newer processor and the 800 G3 only supports up to the Intel 7th gen core processors.

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

Whether you do the firmware upgrade or not, you can still upgrade from W10 > W11 by using a workaround.

If you are happy with your PC, and if you are interested in doing an in-place upgrade from W10 to W11 24H2 on your PC as is, watch this video, which is the easiest way to do it in my opinion, and I have used several different ways to do this during the last 3 years.

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

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

They have been releasing new W11 builds each October so far.

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.
