Initialize-Tpm -AllowClear -AllowPhysicalPresenceThis command initializes a TPM. The *AllowClear* parameter means that a TPM owner authorization value stored in the registry is used to clear the TPM if the TPM is configured to accept TPM_OwnerClear commands. The *AllowPhysicalPresence* parameter means that the cmdlet is allowed to issue a clear request which must be confirmed by a physical present user during the next restart. The cmdlet returns an object with information about the state of the provisioning process. Source: Microsoft, CC BY 4.0; transcript prompt/output removed. This example was not executed.
