- Escrow TPM OwnerAuth
For Windows 7, MBAM must own the TPM for escrow to occur.
For Windows 8.1, Windows 10 RTM and Windows 10 version 1511, escrow of TPM OwnerAuth is supported.
For Windows 10, version 1607 or later, only Windows can take ownership of the TPM. In addiiton, Windows will not retain the TPM owner password when provisioning the TPM. See [TPM owner password](http://technet.microsoft.com/en-us/itpro/windows/keep-secure/change-the-tpm-owner-password) for further details.

You can download the `Invoke-MbamClientDeployment.ps1` script from [Microsoft.com Download Center](https://www.microsoft.com/download/details.aspx?id=54439). This is the main script that your deployment system will call to configure BitLocker drive encryption and record recovery keys with the MBAM Server.
You can download the `Invoke-MbamClientDeployment.ps1` script from [Microsoft.com Download Center](https://www.microsoft.com/download/details.aspx?id=48698). This is the main script that your deployment system will call to configure BitLocker drive encryption and record recovery keys with the MBAM Server.
**WMI deployment methods for MBAM:** The following WMI methods have been added in MBAM 2.5 SP1 to support enabling BitLocker by using the `Invoke-MbamClientDeployment.ps1` PowerShell script.

**PrepareTpmAndEscrowOwnerAuth:** Reads the TPM OwnerAuth and sends it to the MBAM recovery database by using the MBAM recovery service. If the TPM is not owned and auto-provisioning is not on, it generates a TPM OwnerAuth and takes ownership. If it fails, an error code is returned for troubleshooting.
**Note** For Windows 10, version 1607 or later, only Windows can take ownership of the TPM. In addiiton, Windows will not retain the TPM owner password when provisioning the TPM.

See [TPM owner password](http://technet.microsoft.com/en-us/itpro/windows/keep-secure/change-the-tpm-owner-password) for further details.
Depending on its configuration, the Trusted Platform Module (TPM) will lock itself in certain situations ─ such as when too many incorrect passwords are entered ─ and can remain locked for a period of time. During TPM lockout, BitLocker cannot access the encryption keys to perform unlock or decryption operations, requiring the user to enter their BitLocker recovery key to access the operating system drive. To reset TPM lockout, you must provide the TPM OwnerAuth password.

### Escrowing TPM OwnerAuth in Windows 8 and higher
**Note** For Windows 10, version 1607 or later, only Windows can take ownership of the TPM. In addiiton, Windows will not retain the TPM owner password when provisioning the TPM. See [TPM owner password](http://technet.microsoft.com/en-us/itpro/windows/keep-secure/change-the-tpm-owner-password) for further details.
In Windows 8 or higher, MBAM no longer must own the TPM to store the OwnerAuth password, as long as the OwnerAuth is available on the local machine.
To enable MBAM to escrow and then store TPM OwnerAuth passwords, you must configure these Group Policy settings.
