Windows 10: Should I Reset my TPM if I installed a new to me motherboard?

I recently installed a new identical motherboard on an HP Victus 15. When I started the computer up it asks if I want to rest the TPM or boot from current TPM data. The mother board is a used board and I am not sure which rout to take. The original mother board failed and I do have Bitlocker on. Should&n

Move Install to New Motherboard, TPM On/Off, and Fresh Start

Thanks for the reply and the links. In the TPM link, it mentions that only TPM 1.2 can only be turned off and only with Windows 10 Builds 1507 or 1511. I double-checked in tpm.msc and in Windows Security > Device Security > Security Processor Details and
there's no option to turn of my TPM 1.2 in the current Windows 10 build (version 1903, build 18362.418). According to that document:

"You can use the Windows Defender Security Center app to clear the TPM as a troubleshooting step, or as a final preparation before a clean installation of a new operating system. Preparing for a clean installation in this way helps ensure that the
new operating system can fully deploy any TPM-based functionality that it includes, such as attestation. However, even if the TPM is not cleared before a new operating system is installed, most TPM functionality will probably work correctly."

So, I thought to just do a Clear TPM from Windows Security instead, but also according to that document, it will just automatically re-initialize itself afterwards:

"Clearing the TPM resets it to an unowned state. After you clear the TPM, the Windows 10 operating system will automatically re-initialize it and take ownership again."

"...

1. You will be prompted to restart the computer. During the restart, you might be prompted by the UEFI to press a button to confirm that you wish to clear the TPM.
   
2. After the PC restarts, your TPM will be automatically prepared for use by Windows 10."
   

So, if I Clear TPM, do I NOT restart the machine on the current motherboard or before doing a Fresh Start/Reset/Reinstall? Or would it be better to just leave the TPM entirely alone since "most TPM functionality will probably work correctly."

Also, do things like Fresh Start, themselves, notice a TPM is present and prompt to do something with it before wiping the current install?

 

Move Install to New Motherboard, TPM On/Off, and Fresh Start

In the near future, I'll be moving my drive with my current Windows 10 Professional x64 install over to a new motherboard. It's been a very long time since I first installed this system, but I'm fairly sure that my version is a full retail version and that
I can safely move the license to the new system (Settings > Update & Security > Activation shows "Windows is activated with a digital license linked to your Microsoft account", but if it doesn't transfer, I can always buy another license and activate later).
My concerns are:

• On my current system, I have an active TPM, but BitLocker is NOT turned on. So, I won't have to decrypt the drive. But, should I deactivate the TPM before moving the drive over to the new machine? I have no idea if the TPM somehow fingerprints the install
  and locks it to the current motherboard/TPM.
• Similarly, on the new motherboard, should I have its TPM active or inactive when I move the old Windows install over?
• Once I get the old install over to the new machine, I'll do a Fresh Start just to make sure I don't have issues with leftover drivers (I'm going from an Intel setup to an AMD one). Should the TPM be active or inactive when I do the Fresh Start? Will an
  active TPM interfere with a Fresh Start?
  
• And, if things don't go well and I have to do a clean install from something like Microsoft's Windows 10 Media Creation Tool, should the TPM be active or inactive for that?

 

Need help on whether to clear TPM on not

It's clear as mud. As far as I can tell, it's specific to Windows, not necessarily activated programs like MacAfee, games, etc etc etc. MS Office, I have no idea.

Here's a lengthy doc on it: https://docs.microsoft.com/en-us/wi...initialize-and-configure-ownership-of-the-tpm
