1st You must query out Panasonic equipment and machines with Tpm 2.0 set.
WMI namespace: root\CIMV2\Security\MicrosoftTpm
WQL query: SELECT * FROM Win32_Tpm WHERE NOT SpecVersion LIKE “1.2”
2nd You MUST ensure that AC is connected, otherwise the Tpm downgrade will fail. Here is a script I made that tosses a prompt if off AC and loops until AC is plugged in.

And lastly, run the TPMFUac64.exe with the -d argument to execute the downgrade of the Tpm chipset. This will require a reboot, which you can roll into the standard reboot that occurs after the OS is applied.

* TPMFUac64.exe must be requested from your local technical support team.

Hi Brian,
I actually evaluating a toughpad FZ-G1 (FZ-G1P5625KM). It came with windows 7 (TPM 1.2)I need to install windows 10 v1607 on it. I need to upgrade the TPM to 2.0. But I can’t find the TPM 2.0 software for the Panasonic. Would you have a link for it?
Mario, sure here is a link for the downgrade exe:

Did you share the upgrate TPM or Downgrade TPM, i guess Mario is asking to upgrade TPM 1.2 to 2.0
What is when VTx enabled is?
has to be disabled like on HP’s?
