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.
Solved! Go to Solution.
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.
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:
Go to the Dell product support page.
Enter your Service TAG or select your model number from our product list.
Click the Drivers & Downloads tab.
Select Security from the drop-down category box.
Look for Dell TPM 2.0 Firmware update utility.
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.
Follow these steps to flash the TPM with version 1.2 or 2.0 firmware:
TPM.mscto take ownership of 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).
