About this tag
The Host Guardian Service client is a component of Hyper-V that enables shielded virtual machines and TPM-based security. On Windows 11, users may encounter the error 'The Host Guardian Service client configuration settings could not be retrieved' when attempting to apply security changes or enable TPM for a VM.
