Enabling Intel PTT in order to install Win 11 - will this prevent future hardware upgrades?

This is really a general question about both Intel PTT & TPM. I understand that both use embedded data from firmware and hardware to create a 'certified snapshot' of the machine configuration so as to detect illegal and unwanted changes.
Great! But suppose I WANT to make a change such as replacing a hard drive, graphics card or CPU? Will the security of TPM/PTT detect this change and lock-up the machine?
Have I got this wrong?

TPM is there to protect your data, by protection of the software keys and codes used by windows and other security options on your systems, It is manually switchable if you feel you need to switch it off to upgrade hardware, but the only replacement that requires it to be reset AFAIK is a Processor change - It must also be active to install windows 11

If you use bitlocker to encrypt your system drive, then if you change something in the system and reboot, it may lock you out and ask for the bitlocker key to unlock it because the system signature changed. However you can completely avoid this by suspending bitlocker before making such a change, reboot, then enable bitlocker again.

Other than that nothing as far as I know.

As far as I can see, simply enabling PTT in BIOS to install Windows 11 does not actually do anything at all. Hence if you are not actively using any of the security features, then you'll have no trouble with any hardware changes.

I have a similar question, am currently on the Windows 11 insider Beta and will be replacing the current motherboard (Asrock X299) with one from MSI. I intend to just transfer the M.2 PCIe NVME SSD card out that has the operating system on it and slot it into the new motherboard. I will carry out a fresh install at some time but not at the moment. Has anyone any experience of any issues with doing this? Windows 11 is linked to my Microsoft account. My biggest concerns are related to secure boot and TPM being enabled.

Unless it is bitlocker encrypted, you should, in principle, have no issues because of secure boot or TPM. AFAIK, nothing else uses them.

If you have any files or folders encrypted, make sure you create a recovery key for them. IIRC it should be in the file/folder properties advanced.

If you are transferring the OS with the SSD to new hardware with new devices, then you will probably have some issues with drivers that you will have to sort out, including the driver for the nvme SSD (the latter is not an issue if your are currently using the microsoft standard nvme driver). I have done this numerous times and sometimes it takes some finesse. If you do have issues with booting to Windows, try booting to safe mode.

Thanks for the reply. No files or folders are encrypted. The Nvme (WD Black) uses Microsoft drivers. I have done this in the past many times with Sata SSD drives and the main issues that I have had is to realign drive letters with the drive titles because I am OCD enough to have V for videos, W for Work etc. I am also careful not to install manufacturers' motherboard "tuning" and accessory software that can cause problems when switching manufacturers' boards. Will post after I do it if I think that it will help others.

Of course the most important stage is the full backup of your working system - taken immediately prior to the swap ;)
