BitLocker – Taking Ownership of TPM Using Command Line – Windows Vista

If you are using Bitlocker, you will need to initialize TPM chip once the right TPM driver is loaded, which it can be done in two different ways, either by using the TPM MMC (simply type tpm.mcs) or configure it from the command line.

We’ll show you how this is done from the command line using the command line utility manage-bde.wsf which is a WMI based script.

1.    From the Vista Start Menu, locate the Command Prompt shortcut. Right-click the icon and select Run as administrator


2.    Enter the following command:

cscript manage-bde.wsf –tpm –takeownership -<password>

where <password>  should be replaced with your own choice of password

Alternative way to type command line for taking TPM Ownership in BitLocker:

cscript manage-bde.wsf –tpm –o –<password>
where <password>  should be replaced with your own choice of password

In the image as an example as shown below, the <password> is Password!2006

Treat this password as your TPM master password.


3.    The TPM chip is now ready for use.
