Hi GSP57, Let's address the issue you are experiencing with enabling the Trusted Platform Module (TPM) for your Hyper-V virtual machine on a Surface Pro 9 SQ3.
Problem Summary:
You receive the following error:
"Error applying Security changes - The Host Guardian Service client configuration settings could not be retrieved."
Troubleshooting Steps:
1. Check Host Guardian Service Configuration
Ensure that your Host Guardian Service (HGS) is properly configured and running. HGS is necessary for managing shielded VMs and TPM settings.
2. Enable TPM in BIOS/UEFI
- Access UEFI settings:
- Restart your Surface Pro.
- Press and hold the Volume Up button, then press and release the Power button.
- Release the Volume Up button when the Surface logo appears to access the UEFI settings. [*Enable TPM:
- In the UEFI settings, navigate to
Security or a similar section.
- Ensure the TPM option is enabled and active.
3. Verify Hyper-V Settings
[*
Open Hyper-V Manager:
- Right-click your VM and select
Settings. [*Enable TPM:
- Under the
Security section, ensure Enable Trusted Platform Module is checked.
4. Review Group Policy Settings
[*
Open Group Policy Editor:
- Press
Win + R, type gpedit.msc, and press Enter. [*Navigate to:
Computer Configuration -> Administrative Templates -> System -> Device Guard -> Turn on Virtualization-Based Security.- Ensure these settings are configured correctly to support TPM usage.
5. Check Windows and Surface Updates
Ensure that your Windows OS and all relevant drivers are up to date.
6. Use Windows Security
Run a full system scan with Windows Security to ensure no underlying issues interfere with the Hyper-V settings.
7. Examine Event Logs
[*
Open Event Viewer:
- Navigate to
Applications and Services Logs -> Microsoft -> Windows -> Hyper-V-Compute.
- Look for specific errors or warnings related to TPM and Host Guardian Service.
8. Confirm Permissions
Ensure that your account has the necessary permissions to configure TPM and interact with the Host Guardian Service.
