Manually installing TPM and compatible processor on HP ProDesk 600 G1 for Win 11 requirments.

[ShagOvTheMutiny]

Ideally, since the only reasons the computer doesn't meet Windows 11 requirements are hardware related, wouldn't I be able to just install the necessary hardware? Since the TPM is an AUX chip, and the only other issue is the processor, the possability of simply installing the necessities should be enough correct? or if I install a new TPM, is it going to brick my system because it requires a password by BIOS?

Even if you could update the TPM firmware to 2.0 (which you can't since your PC is not one of those on the list that supports a firmware upgrade),

your PC's processor falls way short of Microsoft's minimum W11 processor requirements of an Intel 8th gen core or newer and your PC's motherboard only supports the Intel 4th gens.

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.

So, just so I'm understanding everything, I wouldn't be able to upgrade the processor as is on the current motherboard? The only reason I'm looking for a solution is because I currently run it for home audio production and will need it to be compatible with future program updates.

Other than that I appreciate your insight and response.

That is correct.

The TPM is not the only issue.

If you want a fully supported W11 PC, buy an off lease 600 G4 SFF that has an Intel 8th gen core processor on eBay.

But if you use the workaround I posted, your 600 G1 PC should run just fine on W11.

I have two Dell Optiplex business class PC's which are Dell's equivalent of the 600 G1 which have i5-4590 processors, TPM 1.2 security chips and they run W11 24H2 just fine.
