How can I update TPM on Windows 10 machine for Windows 11?

When preparing my 5-years old Intel Core i7 computer for Windows 11, I ran PC Health Check. These are the results:

Regarding TPM, I tried to upgrade it to 2.0. From Trusted Platform Module (TPM) Management, I cleared TPM ownership and restarted the computer. Then I run TPM 2.0 update utility which I got from Dell. When the computer was restarting, I saw this message for only a few seconds:

UPDATE FAILED. BLOCKED BY TPM FW POLICY

There is nothing promising found on Google search about this. I don't know how to turn off TPM FW Policy, or if FW stands for fireware or something else.

My computer is DELL OptiPlex 7040 with Core i7 3.40GHz processor bought in April 2016.

Solution 1:

According to Dell's own instructions:

A) Make sure you are on the latest UEFI Bios version.
B) Clear the TPM completely (from within UEFI).
C) Try the TPM upgrade patch again.

You probably skipped either A) or B).
