XPS 8700, possible to add a TPM?

Thanks for the update, I have read that the intel ptt module is part of the management engine, and I wonder if anyone knows how to overcome this;

In device Management, System Devices, intel(R) Management Engine Interface:

This device cannot start. (Code 10)

STATUS_DEVICE_POWER_FAILURE

System is Windows 10, Build 19043.

thanks

When I tried to install Windows 11 on my 8700, the installation failed with a message that TPM 2.0 is required. Last night I enabled secure boot in the BIOS and tried again. Windows 11 installed successfully!

Yes, Windows 11 doesn't have to run on this machine. But it so happens that it does (if they don't break it by GA).

BIOS: A14

Processor: Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz Intel64 Family 6 Model 60 Stepping 3

Also, somebody said this machine supports bitlocker (in hardware), I am not sure about that. I have the bitlocker on (company requirement), but I have to enter a password every time I boot the system. I don't have to do it on my other machines with TPM support. 

well... there are posts like this one in the past (2017) suggesting this machine model had a TPM, so it got missing after bios updates? or only some xps 8700 had it?

Windows 10 version 1709 failed to install due to TPM - Microsoft Community

can someone elaborate more about it?

Many devices that don’t have an officially supported CPU may still be able to upgrade to Windows 11 for free, even though Microsoft isn’t recommending the update. However, PCs that don’t meet Microsoft's “hard floor”, which includes a TPM 1.2 chip, a 64-bit CPU, 4GB of RAM, and 64GB of storage won’t be able to upgrade to Windows 11 at all.

It is not just the Haswell chip, it depends on the motherboard and chipset.
The Dell motherboard and chipset does not seem to allow PTT.
Yes you can install Win 11 today but you will be stuck when the final release comes out around October.

I have stopped worrying, Windows 11 is little more than Windows 10 Service Pack 1.
We can just run Win 10 until 2025 but MS will likely extend support beyond 2025.

PS I do own an 8700 so I can say PTT is not there under security in bios.

8700 did not come with Hardware based TPM and does not have a socket.

Secure boot must be on and Legacy CSM must be OFF

Boot must be 64 bit GPT UEFI  MBR is NOT supported.

INTEL PTT was validated in 2012 with 4th Gen Haswell processors and Windows 8.0

Intel PTT is basically the Bios alternative to a the hardware based TPM. Intel PTT works on pretty much every processor/chipset since 4th Gen Core (Haswell) processors were introduced and it even supports BitLocker. This is because Intel PTT supports all Microsoft requirements for firmware Trusted Platform Module (fTPM) 2.0.

I do not own an 8700 so I cant say whether or not PTT is there under security in bios.

Microsoft Giveth and Microsoft taketh away.

Bypass TPM and SecureBoot when installing Windows 11 on unsupported hardware:

https://twitter.com/cadenzza_/status/1408866403743109125

During installation press Shift+F10, open registry and create key

LabConfig under HKEY_LOCAL_MACHINE\SYSTEM\Setup

There add:
"BypassTPMCheck"=dword:00000001
"BypassSecureBootCheck"=dword:00000001

At that screen, you need to press Shift+F10
 to open Command Prompt window and modify the registry.

In Command Prompt, you need to run regedit.exe

and create a new key “LabConfig” under HKEY_LOCAL_MACHINE\SYSTEM\Setup.

 In the “LabConfig” key, create two new entries:

    BypassTPMCheck=dword:00000001
    BypassSecureBootCheck=dword:00000001

Save the changes and compatibility errors will disappear.

****************************************************

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\Setup\LabConfig]

“BypassTPMCheck”=dword:00000001
“BypassSecureBootCheck”=dword:00000001

********************************************************

Method 2: Create your own installation media

The second method involves modifying the ISO file.

If you want to upgrade the operating system by running the setup.exe directly from Windows 11 media image, there’s another simple workaround.

You need to replace the appraiserres.dll in the sources folder on your installation media with the version of that file from a Windows 10 ISO.

Once done, you need to recreate the ISO image using a third-party tool like  Rufus or AnyBurn, and run the setup file again.

Same with me. We have an XPS 8700 in the office with an i7-4790 (3.6 GHz). Upgraded the BIOS from A12 to A14. Still no PTT option under security. Not that a 4th generation Haswell will run Windows 11 but there should be a PTT option according to other posts.

Apologies for my ignorance, but does that mean that the A14 BIOS should have an option to enable or disable PTT yet it doesn't seem to appear for anyone? Is that software capable of enabling PTT?

Could someone test the gigabyte solution to see if this hidden option appears on the A14

@DELL-Chris M Do you know if Dell will release a firmware update for the XPS 8700 to allow enabling of PTT? Thanks!

Allegedly it will be possible to manually install Windows 11 on unsupported hardware:

You’ll be able to run Windows 11 on older PCs—if you install the update manually | Ars Technica

If this is indeed true, and does not just apply to computers with unsupported cpus but with Secure Boot and TPM 1.2 as required by the latest Insider Preview, then life is good.

Sadly, it appears that that Secure Boot and TPM will be required even for manual installations:

Official Windows 11 ISOs will not hard block most PCs with CPUs that aren't officially supported | Windows Central

... in which case we need TPM to be enabled via firmware update on the XPS 8700...

Intel Platform Trust Technology (PTT) is greyed out in F2 Bios under security when
hardware TPM is ON or Enabled.
BIOS "TPM Security" 1.2 must be disabled if listed, since both
TPM and PTT cannot be enabled at the same time.

Tap the F2 key when the Dell logo appears to enter the BIOS
Expand the "Security" section, click "PTT Security",
and deselect Intel Platform Trust Technology
NOTE: If PTT is greyed out as well, re-enable PTT
by disabling Intel Trusted Execution under Virtualization Support.
