TPM 2.0 Support for Dell Optiplex 3020?

Hello, I am trying to verify that my 2 Dell PCs (The Inspiron 17 5767 and Optiplex 3020) are compatible for Windows 11. I am trying to figure out if my Dell Optiplex 3020 supports TPM 2.0. The Firmware Update Utility says that I have a TPM 2.0 update. Is this right and does my computer support TPM 2.0? My BIOS Revision for my system in A20.

that's awesome, I have some Intel(R) Core(TM) i5-4590T 3020s, I'd hate to abandon them


Advance, Windows Insider, versions of Win 11 will run on older hardware.  This does not diminish the fact that Microsoft is still sticking with 8th gen Intel CPU and later when the "final" release to the public version is made available.  Requirements may change by the time its released to the public but for now we must assume their 8th gen is minimum.

Microsoft has softened their stance however allowing TPM 1.2

This is probably a response to FED and STATE government concerns that they wont be fully updated to new hardware by 2025.

I have Windows 11 (from the ISO) working on a 3020 SFF with 4690K CPU. 

I had to make a Registry change and affirm that the configuration is unsupported. Still, once the main installation was complete, Windows Update made available updates which downloaded and installed without issue.


exactly  how did you do it in laymans terms


what registry change did you make Thanks


Dell computers that were built between 2015 and 2018 may have shipped from the factory with Trusted Platform Module (TPM) firmware version 1.2.

This article lists the computer models that may have shipped with TPM 1.2 so you can upgrade the TPM firmware to version 2.0 if needed.

Computers that were released after 2019 support TPM firmware 2.0 without an option to downgrade 

To confirm that your computer can update to TPM firmware version 2.0:

  1. Go to the Dell product support page.

  2. Enter your Service TAG or select your model number from our product list.

  3. Click the Drivers & Downloads tab.

  4. Select Security from the drop-down category box.

  5. Look for Dell TPM 2.0 Firmware update utility.

  6. If it is listed, it confirms you can run the update.

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.

NOTE: Never flash the computer’s TPM with the firmware from a different computer. This may result in damage to the TPM.

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.
NOTE: To automate this process, see the Dell knowledge base article Using scripting or automation for TPM firmware updates from Dell.

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).
