Got a new Windows 11 system without a TPM

johnpd · Jul 24, 2024

I am helping someone who got a new mini computer but a TPM was not installed on it. He has mentioned this to the manufacturer, but he can't convince them to send him a replacement. He got it with Windows 11 v22H2. It was getting updates fine until earlier this year when Windows attempted to install the 23H2 upgrade. It complained about the missing TPM. Is there some way around this? If he tried the enablement package for v23H2, would that work? At this point he cannot even install any normal updates.

When did he buy it? what is the exact make and model? Do you know the make of the motherboard and the type of processor? In the UK he would be entitled to return it as not fit for purpose as it can't be kept up to date. Is your friend in Arizona?

This tutorial will show you how to bypass the TPM requiement.

I run 11 on several unsupported devices. Yes, the 23H2 enablement package will install without making any hardware checks. You can download it here:

As for the missing TPM, a mini-PC is more akin to a laptop than a desktop in design and construction. None of my fully supported laptops have a separate TPM, what they do have is a firmware version of TPM as a part of their CPU chipset. If the mini-PC has this, then it may need enabling in the BIOS. For AMD this will be named fTPM, and for Intel it's called Platform Trust Technology (PTT), both of which meet Windows 11 hardware requirements. What is the make and model of the PC's CPU?

He bought a MeLE Quieter 3C in September 2023. This is a small fanless computer. I have a similar one but a little later upgraded version. He has Windows 11 Pro installed. I am not sure what motherboard he has. I know the BIOS is from Aptio, I believe the board is from AMI. It ran fine until Windows Update tried to install 23H2. He actually lives in France.

This is a screen print of his BIOS setting regarding TPM.

Maybe it does have TPM but version 1.2 not the 2.0 required for full compliance. Just use the 23H2 Enablement Package to upgrade to 23H2 or see relevant threads to bypass compatibility check and upgrade from the ISO.

Thanks, I passed the suggestion to him.

New computers has the TPM on the CPU.
All Ryzen CPU's have a TPM built into the CPU
All 8th Generation or later Intel® Core™ Processor family have a TPM built into the CPU
What CPU brand and model does it has?

That machine is spec'd as having a Celeron N5105 CPU. That's recent enough (2021 release) that I'd hope the motherboard for it supports PTT (platform trust technology, Intel's firmware TPM).

Unfortunately, I don't find a downloadable manual for its BIOS settings. PTT is the thing to look for.

spapakons · Jul 24, 2024

Don't worry, bypass compatibility check to install Windows 11 and you can activate TPM any time you find it, if it exists. When you have the time, boot to BIOS and examine carefully all options. Maybe you must switch to UEFI boot and enable Secure Boot before other security settings are revealed.

johnpd · Jul 25, 2024

The TPM is not present. He tried the Enablement Package and ended up with the same problem.

Neither that option nor Device Manager shows the TPM.

The 23H2 Enablement Package works if you already run Windows 11 22H2 build 22621.1506 or higher. If you have 21H2 you must either first upgrade to 22H2 or use the ISO to upgrade directly from 21H2 to 23H2. If you have 22H2 but lower build number, run Windows Update to reach build 22621.1506 or higher and then run the Enablement Package. I confirm that it DOESN'T check compatibility, I have used it on two or more unsupported PCs and switched from 22H2 to 23H2 without using any hack, without having to disconnect from the internet like when doing a full upgrade from the ISO. Ideal for upgrading your friend's unsupported computer remotely by AnyDesk or similar utility.

Celeron N5105 CPU If that is the CPU then it will have the Intel PTT which needs to be enabled.

Going by post #5 That shows it is not enabled.

I guess the [Enable] needs to be showing either [Enabled] or [On]?

To do that should be somewhere else in the BIOS settings.
You need to look, maybe just down that page, or somewhere in the security related stuff, the wording is likely to be very non-understandable techno babble.
May not be as simple as PTT > On.

The manufacturer of the PC/Laptop should have the info as the BIOS/UEFI is written/modded for them.

Intel PTT and AMD fTPM are CPU based TPM and equate to TPM 2.0 certainly should do with a 2021 CPU.

If you see carefully the screenshot in port #5 the BIOS setting is Enable but at the bottom is reads No security device found. So there is no TPM device present. Never mind, just bypass compatibility check and use Windows 11 unsupported like all of us. We will be glad to provide you all the support you need. Much quicker and more helpful than contacting Microsoft Support

Helmut · Jul 25, 2024

"So there is no TPM device present."

Does not matter what that says, I did read it, may just refer to a physical TPM module, not what is embedded in the CPU.

We cannot see all the BIOS setting pages related to Security, the OP can.

What has this got to do with MS support, it is the domain of the PC/Laptop manufacturer and their BIOS/UEFI supplier.

Why introduce all this complex tangential junk to consumers.

For profit of course. They have teamed up with Manufacturers and try to convince us to replace our "obsolete" computer in order to run Windows 11. Unlike Apple they don't block "unsupported" computers entirely, they let them install Windows 11 if you bypass compatibility check. I read somewhere that the Registry hack to bypass compatibility check for a clean installation was leaked by Microsoft.

No, not so much 'leaked' - more like 'published' :wink:

Microsoft said:
Warning:

Microsoft recommends against installing Windows 11 on a device that does not meet the Windows 11 minimum system requirements. If you choose to install Windows 11 on a device that does not meet these requirements, and you acknowledge and understand the risks, you can create the following registry key values and bypass the check for TPM 2.0 (at least TPM 1.2 is required) and the CPU family and model.

Registry Key: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup

Name: AllowUpgradesWithUnsupportedTPMOrCPU

Type: REG_DWORD

Value: 1

Just use dism /Apply-Image to the target computer and install the bootloader via bcdboot.exe.

Zillions of posts on how to do this so not repeating stuff again.

You can also ensure a local account by at the sign in at the ist OOB login choose work/schoolcomputer and select domain login -- this still works at least on any PRO version of W11 -- can't say about W11 Home though as I don't have that one.
