Unlike previous versions of Windows, Vista's "diskpart" command-line tool includes the ability to shrink the size of an NTFS volume so that this volume may be created from already allocated space. A tool called the BitLocker Drive Preparation Tool is also available from Microsoft that allows an existing volume on Windows Vista to be shrunk to make room for a new boot volume and for the necessary 604:(EFS) may be used in conjunction with BitLocker to provide protection once the operating system is running. Protection of the files from processes and users within the operating system can only be performed using encryption software that operates within Windows, such as EFS. BitLocker and EFS, therefore, offer protection against different classes of attacks. 38: 522:: The user must insert a USB device that contains a startup key into the computer to be able to boot the protected OS. Note that this mode requires that the BIOS on the protected machine supports the reading of USB devices in the pre-OS environment. BitLocker does not support smart cards for pre-boot authentication. 786:
Starting with Windows 8 and Windows Server 2012, Microsoft removed the Elephant Diffuser from the BitLocker scheme for no declared reason.

In September 2019 a new update was released (KB4516071) changing the default setting for BitLocker when encrypting a self-encrypting hard drive. Now, the default is to use software encryption for newly encrypted drives. This is due to hardware encryption flaws and security concerns related to those

In Active Directory environments, BitLocker supports optional key escrow to Active Directory, although a schema update may be required for this to work (i.e. if the Active Directory Services are hosted on a Windows version previous to Windows Server 2008).

BitLocker was briefly called Secure Startup before Windows Vista's 566:, the whole drive or more than one drive.) When enabled, TPM and BitLocker can ensure the integrity of the trusted boot path (e.g. BIOS and boot sector), in order to prevent most offline physical attacks and boot sector malware. 592:
