Hi Everyone,
Motherboard: MSI B550-A PRO
CPU: AMD Ryzen 7 3700X
My PC runs on Windows 11 Pro, but under 'Security processor details,' it states: "Attestation: Not supported."
I tried the following to resolve this issue, but without success:
- Installing the latest Windows updates and drivers, including the most recent version of the BIOS (version 7C56vAJ1) and chipset (AMD Chipset Driver 6.10.22.027) from my motherboard manufacturer's website.
- In the BIOS: enabling and disabling secure boot, clearing the TPM, enabling and disabling TPM, and rebooting in between.
- Clearing the TPM via 'TPM.msc.'
- Reinstalling Windows after performing all the above steps.
I did not buy a TPM module.
After extensive online research, I discovered that one (or more) certificates related to the TPM are missing, likely the "EK cert" or similar. I read that this might be related to the fTPM of my processor.
Could you please hele resolve this issue?
Please see below for more information
I look forward to your response.
