This topic provides a high-level overview of BitLocker, including a list of system requirements, practical applications, and deprecated features.
BitLocker overview
The version of BitLocker, included in Windows 7 and Windows Server 2008 R2, adds the ability to encrypt removable drives. On Windows XP or Windows Vista, read-only access to these drives can be achieved through a program called BitLocker To Go Reader, if FAT16, FAT32 or exFAT filesystems are used. May 06, 2019 If you want to use standard BitLocker encryption instead, it's available on supported devices running Windows 10 Pro, Enterprise, or Education. Some devices have both types of encryption. For example, a Surface Pro which runs Windows 10 Pro has both the simplified device encryption experience, and the full BitLocker management controls. Windows Server 2008, Windows Vista Enterprise, Windows Vista Enterprise 64-bit edition, Windows Vista Service Pack 1, Windows Vista Ultimate, Windows Vista Ultimate 64-bit edition Note: BitLocker does not need to be installed on the computer for you to use the BitLocker Drive Preparation Tool, but the system must be running. How to Retrieve BitLocker Recovery Key in Windows 10. If BitLocker has problems unlocking the drive, you may need a recovery key to continue. To help retrieve previously stored BitLocker recovery keys, this article describes the different storage options for finding your BitLocker recovery key. Qualcomm usb driver windows 7.
BitLocker Drive Encryption is a data protection feature that integrates with the operating system and addresses the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned computers.
BitLocker provides the most protection when used with a Trusted Platform Module (TPM) version 1.2 or later. The TPM is a hardware component installed in many newer computers by the computer manufacturers. It works with BitLocker to help protect user data and to ensure that a computer has not been tampered with while the system was offline.
On computers that do not have a TPM version 1.2 or later, you can still use BitLocker to encrypt the Windows operating system drive. However, this implementation will require the user to insert a USB startup key to start the computer or resume from hibernation. Starting with Windows 8, you can use an operating system volume password to protect the operating system volume on a computer without TPM. Both options do not provide the pre-startup system integrity verification offered by BitLocker with a TPM.
In addition to the TPM, BitLocker offers the option to lock the normal startup process until the user supplies a personal identification number (PIN) or inserts a removable device, such as a USB flash drive, that contains a startup key. These additional security measures provide multifactor authentication and assurance that the computer will not start or resume from hibernation until the correct PIN or startup key is presented.
Practical applications
Data on a lost or stolen computer is vulnerable to unauthorized access, either by running a software-attack tool against it or by transferring the computer's hard disk to a different computer. BitLocker helps mitigate unauthorized data access by enhancing file and system protections. BitLocker also helps render data inaccessible when BitLocker-protected computers are decommissioned or recycled.
There are two additional tools in the Remote Server Administration Tools, which you can use to manage BitLocker.
BitLocker Recovery Password Viewer. The BitLocker Recovery Password Viewer enables you to locate and view BitLocker Drive Encryption recovery passwords that have been backed up to Active Directory Domain Services (AD DS). You can use this tool to help recover data that is stored on a drive that has been encrypted by using BitLocker. The BitLocker Recovery Password Viewer tool is an extension for the Active Directory Users and Computers Microsoft Management Console (MMC) snap-in.By using this tool, you can examine a computer object's Properties dialog box to view the corresponding BitLocker recovery passwords. Additionally, you can right-click a domain container and then search for a BitLocker recovery password across all the domains in the Active Directory forest. To view recovery passwords, you must be a domain administrator, or you must have been delegated permissions by a domain administrator.
BitLocker Drive Encryption Tools. BitLocker Drive Encryption Tools include the command-line tools, manage-bde and repair-bde, and the BitLocker cmdlets for Windows PowerShell. Both manage-bde and the BitLocker cmdlets can be used to perform any task that can be accomplished through theBitLocker control panel, and they are appropriate to use for automated deployments and other scripting scenarios. Repair-bde is provided for disaster recovery scenarios in which a BitLocker protected drive cannot be unlocked normally or by using the recovery console.
New and changed functionality
To find out what's new in BitLocker for Windows 10, such as support for the XTS-AES encryption algorithm, see the BitLocker section in 'What's new in Windows 10.'
System requirements
BitLocker has the following hardware requirements:
For BitLocker to use the system integrity check provided by a Trusted Platform Module (TPM), the computer must have TPM 1.2 or later. If your computer does not have a TPM, enabling BitLocker requires that you save a startup key on a removable device, such as a USB flash drive.

A computer with a TPM must also have a Trusted Computing Group (TCG)-compliant BIOS or UEFI firmware. The BIOS or UEFI firmware establishes a chain of trust for the pre-operating system startup, and it must include support for TCG-specified Static Root of Trust Measurement. A computer without a TPM does not require TCG-compliant firmware.

Important
From Windows 7, you can encrypt an OS drive without a TPM and USB flash drive. For this procedure, see Tip of the Day: Bitlocker without TPM or USB.
Note
TPM 2.0 is not supported in Legacy and CSM Modes of the BIOS. Devices with TPM 2.0 must have their BIOS mode configured as Native UEFI only. The Legacy and Compatibility Support Module (CSM) options must be disabled. For added security Enable the Secure Boot feature.
Installed Operating System on hardware in legacy mode will stop the OS from booting when the BIOS mode is changed to UEFI. Use the tool MBR2GPT before changing the BIOS mode which will prepare the OS and the disk to support UEFI.
The hard disk must be partitioned with at least two drives:
- The operating system drive (or boot drive) contains the operating system and its support files. It must be formatted with the NTFS file system.
- The system drive contains the files that are needed to load Windows after the firmware has prepared the system hardware. BitLocker is not enabled on this drive. For BitLocker to work, the system drive must not be encrypted, must differ from the operating system drive, and must be formatted with the FAT32 file system on computers that use UEFI-based firmware or with the NTFS file system on computers that use BIOS firmware. We recommend that system drive be approximately 350 MB in size. After BitLocker is turned on it should have approximately 250 MB of free space.
When installed on a new computer, Windows will automatically create the partitions that are required for BitLocker.

When installing the BitLocker optional component on a server you will also need to install the Enhanced Storage feature, which is used to support hardware encrypted drives.
