Thank you for your summary.

1. Yes, on the Dell support page my Precision 3590 is listed for Dell Trusted Device, and the software was pre-installed.

2. The BIOS is up to date, version 1.19.1.

3. TPM 2.0 is enabled and the new CA 2023 keys are installed.

4. The Windows version is current (10.0.26200 Build 26200, Insider).

5. All drivers are up to date (according to Dell SupportAssist and Dell Update).

The critical events were generated by Dell apps like:

- Dell Diagnostics (mainly)

- DellEnterpriseClientFrameworkSubAgent

It’s time to remove these Dell tools. I don’t see the benefit — they generate errors and slow down the computer.

Dell seems to work on the issue. This shows the "improved" status with BIOS 1.20.0

New BIOS, same issue

I will not pursue this thread any further — it is what it is.
