Descripción detallada

The Set-TpmOwnerAuth cmdlet changes the current owner authorization value of the Trusted Platform Module (TPM) to a new value. You can specify the current owner authorization value or specify a file that contains the current owner authorization value. If you do not specify an owner authorization value, the cmdlet attempts to read the value from the registry.

Use the ConvertTo-TpmOwnerAuth cmdlet to create an owner authorization value. You can specify a new owner authorization value or specify a file that contains the new value.

An owner authorization file is not a simply a password. It is generated for a specific system. 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.

Ejemplos

Example 1: Replace imported owner authorization value

This command replaces the current owner authorization value with the specified owner authorization value. The command does not specify the current owner authorization value, so the cmdlet attempts to find it in the registry. This command does not import the owner authorization value into the registry. After you run this command, you can use the Import-TpmOwnerAuth cmdlet to import the new value into the registry, if necessary.

PS C:\> Set-TpmOwnerAuth -NewOwnerAuthorization "h4FCmNeWVNp5IMHxRfFL9QEq4vM="

Example 2: Replace owner authorization value with value in file

This command replaces the current owner authorization value with the owner authorization value in the specified file.

PS C:\> Set-TpmOwnerAuth -NewFile "NewOwnerAuth.tpm"

Example 3: Replace owner authorization value

This command replaces the specified owner authorization value with a new owner authorization value.

PS C:\> Set-TpmOwnerAuth -OwnerAuthorization "oaVq17hNcFS2KSnHwpZa4AlrWBo=" -NewOwnerAuthorization "h4FCmNeWVNp5IMHxRfFL9QEq4vM="
