Windows 11 Windows 10 - Dell Workstation TPM 2.0 firmware update procedure - 100% Working

If you have a Dell product with an available TPM firmware update ( TPM1.2 >>> TPM2.0) you may find the firmware update process does not complete or fails due to an "ownership" conflict. If you are running Windows 10 or 11, at the first boot the Operating System will undertake "provisioning" and when this happens you wont be able to easily update the firmware because ownership is registered in the TPM module. 

To overcome this problem I have found the method below works for Precision Workstation T7810, results may vary but it will most likely work for every TPM 2.0 update as the fundamentals will always be very similar or the same. 

I am giving the most basic notes and I am assuming you have basic Windows skills under CMD, PowerShell and Search and you know how to open CMD or PowerShell as Administrator

For this to work your TPM must be ON and ENABLED (two settings found for TPM found in F2 BIOS menu under SECURITY) 

Step 1: Disable TPM provisioning 

In your Windows environment

Open POWERSHELL as Administrator and execute the following command 

Disable-TpmAutoProvisioning

 

Step 2: Open the TPM  control panel 

In your Windows environment

Search for TPM.MSC, open this control app 

Under actions hit CLEAR TPM 

Your computer will reboot

 

Step 3: Update TPM firmware 

In your Windows environment

Download and run the suitable DELL TPM firmware update required for your machine

Most likely TPM 2.0 firmware

Your computer will reboot 

Your computer will go into FLASH MODE

You computer will reboot.

If there is a long delay of several minutes you may have to long-press the power ON button. 

 

Step 4: F2 BIOS settings 

In your BIOS environment

At bootup press F2 BIOS and set all parameters to DEFAULT to clear out all prior bios parameters

Exit

You computer will reboot

Your computer may reboot 2 to 5 times depending on the hardware configuration. Do not be alarmed by this frequent reboot and prolonged boot time. 

 

Step 5: F2 Check bios settings

In your BIOS environment

Enter F2 BIOS and confirm the settings are according to your preferences

Apply

Exit

You computer will reboot

 

Step 6: Enable TPM provisioning 

In your Windows environment

Open POWERSHELL as Administrator and execute the following command 

Enable-TpmAutoProvisioning

Reboot

 

Step 7: Confirm TPM 2.0 in Device Manager 

In your Windows environment open Device Manager 

Why do you need this feature ? 

- Windows 11 installation

- Enable NVME bootup from PCIe slot (this appears to be the case with T7810 and T5810)
