Detailed Description

The Initialize-Tpm cmdlet performs part of the provisioning process for a Trusted Platform Module (TPM). Provisioning is the process of preparing a TPM to be used. You may need to perform other steps to fully provision a TPM.

For more information on TPM, see the Trusted Platform Module Technology Overview in the Technet library at https://technet.microsoft.com/en-us/library/jj131725.aspx.

The output type is the type of the objects that the cmdlet emits.

  • TpmProvisioningObject

    This cmdlet returns a TpmProvisioningObject object that includes the following information:

    -- TpmReady. Whether the TPM is complies with Windows Server® 2012 standards.
    -- RestartRequired. Whether the computer requires a restart to continue the provisioning process.
    -- ShutdownRequired. Whether the computer must be shut down to continue the provisioning process.
    -- ClearRequired. If this has a value of True, you must import an owner authorization value or remove the owner authorization value.
    -- PhysicalPresenceRequired. Whether a person must be at the computer during restart to continue the provisioning process.

Examples

Example 1: Initialize a TPM

This command initializes a TPM. The ForceClearAllowed parameter means that the owner authorization value needs to be imported or reset in order for provisioning to continue. The PhysicalPresenceAllowed parameter means that a user must be present during a restart to continue the process.

The cmdlet returns an object with information about the state of the provisioning process.
