As you all know, a major stumbling block for upgrading to Windows 11 will be the requirement for TPM 2.0. I am wondering whether anyone knows whether my otherwise solid desktop has motherboard support to plug in a TPM module? Or am I just being forced to live with Windows 10? (Or buy a new desktop?)

I highly recommend that you read:
What is TPM 2.0: how to know if you have it and how to activate it in the BIOS - Techidence
for details on TPM, and how to tell if your prcoessor includes TPM.
Maybe, you can upgrade the processor on your computer to one that includes TPM.

Hi@MSGlobeTrotter,
Thank you for posting on HP Support Community.
I suggest you update the BIOS from this Link: https://hp.care/2MznadV
Also, clear the TPM cache
-
Open the TPM MMC by typing tpm.msc in the service box
-
If the User Account Control dialogue box appears, confirm that the action it displays is what you want, and then click Yes.
-
Under Actions, click Clear TPM.
-
You will be prompted to restart the computer. During the restart, you might be prompted by the UEFI to press a button to confirm that you wish to clear the TPM.
-
After the PC restarts, your TPM will be automatically prepared for use by Windows 10.
You can refer to these Links: https://hp.care/2JIsmOZ and https://hp.care/2LebHit
Hope this helps! Keep me posted.

I really appreciate your response but I don't seem to be any closer to resolving this:
- The link you provided took me to drivers for "HP Pavilion Notebook - 15-ab104ur"
Somehow I doubt you'd want me to install that BIOS on my "ENVY Desktop - 750-150xt CTO"
- Or do you really intend that?
- I went to the drivers page for my model.
- I downloaded and installed the most recent date for BIOS:
A0.17 Rev.A 14.7 MB May 14, 2018 - I rebooted via Windows to UEFI firmware settings.
- I checked the UEFI firmware BIOS settings to see if there was any TPM reference for the Intel Core(TM) i5-4690K
and /or options for turning TPM on for that processor. There was none in the settings. - I booted into Windows 10.
- I ran TPM.MSC. It tells me:
"Compatible Trusted Platform Module (TPM) cannot be found on this computer."
Any other ideas? Once Windows 11 starts appearing, there will be other owners asking about this.
