NAME

SYNOPSIS
    Resets a TPM to its default state.
    
    
SYNTAX
    Clear-Tpm [[-OwnerAuthorization] ] []
    
    Clear-Tpm -File  []
    
    
DESCRIPTION
    The Clear-Tpm cmdlet resets the Trusted Platform Module (TPM) to its default state. A reset removes the owner 
    authorization value and any keys stored in the TPM. To reset a TPM, you must provide a valid owner authorization 
    value. You can enter an owner authorization value or specify a file that contains the value. If you do not provide 
    a value, the cmdlet attempts to use a value stored in the registry.
    
    For more information on TPM, see the Trusted Platform Module Technology Overview 
    (http://technet.microsoft.com/en-us/library/jj131725.aspx) in the TechNet library.

OUTPUTS
        TpmObject

        -- TpmReady. Whether a TPM complies with Windows Serverr 2012 standards.
        -- TpmPresent. Whether there is a TMP on the current computer.

        are Legacy, Balanced, and Full.
        -- OwnerClearDisabled. Whether TPM can be reset. If this value is True, the TPM cannot be reset through the 
        operating system by using the owner authorization value. If this value is False, the TPM can be reset through 
        the operating system. 
        -- AutoProvisioning. Whether the computer can use auto-provisioning. Possible values are NotDefined, Enabled, 
        Disabled, and DisabledForNextBoot.
        -- LockedOut. Whether a TPM is locked out.
        -- SelfTest. Information returned by a test that TPM runs.
    
    
    Example 1: Reset TPM
    
    PS C:\> Clear-Tpm
    TpmReady           : False
    TpmPresent         : True
    ManagedAuthLevel   : Full
    OwnerAuth          :
    OwnerClearDisabled : True
    AutoProvisioning   : Disabled
    LockedOut          : False
    SelfTest           : {191, 191, 245, 191...}

    specifying a value or using a value in a file.
    
    
    Example 2: Reset TPM with a supplied authorization value
    
    PS C:\> Clear-Tpm -OwnerAuthorization "vjnuW6rToM41os3xxEpjLdIW2gA="
    TpmReady           : False
    TpmPresent         : True
    ManagedAuthLevel   : Full
    OwnerAuth          : OwnerClearDisabled : True
    AutoProvisioning   : Disabled
    LockedOut          : False
    SelfTest           : {191, 191, 245, 191...}
    
    This command resets the TPM by using the specified owner authorization value.
    
    
    Example 3: Reset TMP using authorization value from file
    
    PS C:\> Clear-Tpm -File "MyOwnerAuthFile.tpm"
    TpmReady           : False
    TpmPresent         : True
    ManagedAuthLevel   : Full
    OwnerAuth          :
    OwnerClearDisabled : True
    AutoProvisioning   : Disabled
    LockedOut          : False
    SelfTest           : {191, 191, 245, 191...}
