TPM 2.0 Support for Dell Optiplex 3020?

How to Flash TPM Firmware and Change TPM Modes

TPM 1.2 and 2.0 modes can be changed, only by the use of firmware that is downloaded from the Dell Drivers & Downloads website. This is feature is supported by select Dell computers. You can use the table in the above section to determine if a computer supports this feature. You can also check the Dell Drivers & Downloads website to verify if the firmware is available for switching between the two modes. If the firmware is not listed, then a computer does not support this feature. In addition, the TPM must be On and Enabled in order to flash the firmware.

Follow these steps to flash the TPM with version 1.2 or 2.0 firmware:

1. In Windows
   1. Suspend BitLocker or any encryption or security program relying on the TPM.
   2. Disable Windows Auto Provisioning if needed (Windows 8 or 10).
      1. PowerShell command: Disable-TpmAutoProvisioning
   3. Reboot the computer and go into the BIOS.
2. In the BIOS screen
   1. Go to Security and then the TPM/Intel PTT page.
   2. Check the Clear TPM box and press the "Apply" button at the bottom.
   3. Press the "Exit" button to reboot into Windows.
3. In Windows
   1. Run the TPM firmware update.
      1. The computer automatically reboots and begins the firmware flash.
      2. Do NOT turn the computer off during this update.
   2. Reboot computer into Windows and enable Windows Auto Provisioning, if applicable.
   3. PowerShell command: Enable-TpmAutoProvisioning
   4. If running Windows 7, use TPM.msc to take ownership of the TPM.
   5. Reboot the computer again and enable any encryption that uses the TPM.

The TPM firmware version can be checked using TPM.msc or the get-tpm command in Windows PowerShell (supported in Windows 8 and 10 only). Using get-tpm on Windows 10 1607 and earlier only shows the first 3 characters of the firmware (listed as ManufacturerVersion) (Figure 3). Windows 10 1703 and later shows 20 characters (listed as ManufacturerVersionFull20) (Figure 4).
