Unlike a standard BitLocker implementation, device encryption is enabled automatically so that the device is always protected. When a clean installation of Windows is completed and the out-of-box experience is finished, the device is prepared for first use. As part of this preparation, device encryption is initialized on the OS drive and fixed data drives on the computer with a clear key that is the equivalent of standard BitLocker suspended state. In this state, the drive is shown with a warning icon in Windows Explorer. The yellow warning icon is removed after the TPM protector is created and the recovery key is backed up.

In the search box on the taskbar, type Manage BitLocker and then select it from the list of results. Or, select Start > Settings > Privacy & security > Device encryption > BitLocker drive encryption.

Note: You'll only see this option if BitLocker is available for your device. It isn't available on Windows 11 Home edition.

Windows Mobile 6.5, Windows RT and core editions of Windows 8.1 include device encryption, a feature-limited version of BitLocker that encrypts the whole system.[20][21][22] Logging in with a Microsoft account with administrative privileges automatically begins the encryption process. The recovery key is stored to either the Microsoft account or Active Directory (Active Directory requires Pro editions of Windows), allowing it to be retrieved from any computer. While device encryption is offered on all editions of Windows 8.1, unlike BitLocker, device encryption requires that the device meet the InstantGo (formerly Connected Standby) specifications,[22] which requires solid-state drives and a TPM 2.0 chip.[20][23]

In September 2019 a new update was released (KB4516071[25]) 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 issues.[26]

BitLocker is a logical volume encryption system. (A volume spans part of a hard disk drive, 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.[35]

Once an alternate boot partition has been created, the TPM module needs to be initialized (assuming that this feature is being used), after which the required disk-encryption key protection mechanisms such as TPM, PIN or USB key are configured.[38] The volume is then encrypted as a background task, something that may take a considerable amount of time with a large disk as every logical sector is read, encrypted and rewritten back to disk.[38] The keys are only protected after the whole volume has been encrypted when the volume is considered secure.[39] BitLocker uses a low-level device driver to encrypt and decrypt all file operations, making interaction with the encrypted volume transparent to applications running on the platform.[38]

According to Microsoft sources,[48] BitLocker does not contain an intentionally built-in backdoor, so there is no Microsoft-provided way for law enforcement to have guaranteed access to the data on a user's drive. In 2006, the UK Home Office expressed concern over the lack of a backdoor and tried entering into talks with Microsoft to get one introduced.[49] Microsoft developer and cryptographer Niels Ferguson denied the backdoor request and said, "over my dead body".[50] Microsoft engineers have said that United States Federal Bureau of Investigation agents also put pressure on them in numerous meetings to add a backdoor, although no formal, written request was ever made; Microsoft engineers eventually suggested that agents should look for the hard copy of the encryption key that the BitLocker program suggests that its users make.[51]

If you've never used BitLocker, the feature offers two methods of encryption: hardware-based encryption using a Trusted Platform Module (TPM) chip and software-based encryption using a password or USB flash drive to decrypt the drive and continue booting. Also, the feature protects the data on the installation drive, secondary storage, and removable media with "BitLocker To Go."

If the computer does not have a Trusted Platform Module chip, you won't be able to configure BitLocker on Windows 10. However, you can still use encryption if you use the Local Group Policy Editor to enable additional authentication at startup. Once the feature is enabled, you will need to provide a password or USB flash drive with the recovery key to unlock the drive and continue with the computer startup process.

When using encryption, always try to start with an empty drive to speed up the process. Then, the data will encrypt quickly and automatically. In addition, similar to the feature of the operating system drive, you will get the same additional options and a few more, including:

BitLocker Drive Encryption, or BitLocker, is a Microsoft Windows security and encryption feature that is included with certain newer versions of Windows. BitLocker enables users to encrypt everything on the drive Windows is installed on, protecting that data from theft or unauthorized access.

Although BitLocker first debuted with Windows Vista in 2007, beginning with Windows 10 version 1511, Microsoft updated BitLocker, introducing new encryption algorithms, new group policy settings, new operating system (OS) drives and removable data drives. This update applies to Windows 11, 10 and Server 2016 and above. BitLocker itself works on Pro, Enterprise and Education editions of Windows.

After turning BitLocker on, Windows begins checking system settings. The user must create a password, which is needed every time they access their PC or drive. The user then selects Recovery key settings. After clicking on Next, the user can select how much of their drive they wish to encrypt. The two-volume encryption options are to encrypt used disk space only or to encrypt the entire drive. Encrypt used disk space refers to only the disk space that contains data, while encrypt the entire drive means that the entire storage volume, including free space, is encrypted.

BitLocker Drive Encryption is a native security feature that encrypts everything on the drive that Windows is installed on. Device encryption helps protect your data by encrypting it. Only someone with the right encryption key (such as a personal identification number) can decrypt it.

I have a HD protected by Bitlocker. Login, password and restorekey are unknown and all I want to do is wipe the whole drive. When I try to boot from a windows installation cd I have no access to the drive since it asks for the restore key I don't have.

You dont absolutely need DBAN, GParted or another third party tool. Just Bootup WindowsPE (e.g. with a windows installation media on USB Stick or DVD) and use the windows format command to format the drive. When you have a Bitlocker encrypted drive, you just need to securely delete its encryption keys. For this its enough to format the drive.

Using DISKPART to remove all partitions worked for me.If bitlocker is mandatory then first fully update windows and drivers and bios before enabling bitlocker. Otherwise you will need to do all the tedious stuff like pausing protection on/off after each reboot update.

If Bitlocker encryption is enabled, the storage location of the content present in the encrypted drive of the imaging computer cannot be identified. Hence, decrypting the contents of the bitlocker encrypted drive is essential for efficient imaging.

To disable bitlocker using command line, ensure that you have logged onto Admin user account to turn off bitlocker encryption. Follow the steps given below to turn off bitlocker encryption using Command Prompt.

You can ensure if the BitLocker encryption is removed by checking if the Bitlocker lock icon is removed in the particular drive and by accessing the particular drive. You can repeat the same steps to disable Bitllocker Encryption in other drives.

Note: If the partition with the operating system contains any automatic unlocking keys, the cmdlet to disable bitlocker encryption will not work. You can use the Clear-BitLockerAutoUnlock cmdlet in Powershell window to remove all automatic unlocking keys to disable BitLocker for the partition.

Are you all having this issue on the same Samsung 990 drive?
We have run through validation with other drives which do not have an issue with bitlocker.
But I do not think we validate encryption explicitly using hardware OPAL SED support.

BitLocker would be the best solution in my personal experience with drive encryption in general. The issue with BitLocker is it requires a TPM, I don't know if AWS's hardware presents a TPM or not. If it doesn't I would say TrueCrypt is next best option but requires you to type in the decryption password every time you start the machine.

On all devices that meet the BitLocker hardware requirements (see the previous section for details), device encryption is automatically enabled. Windows Setup automatically creates the necessary partitions and initializes encryption on the operating system drive with a clear key. To complete the encryption process, you must perform one of the following steps:

On self-encrypting solid-state drives that support hardware encryption, Windows will offload the work of encrypting and decrypting data to the hardware. Note that a vulnerability in this feature, first disclosed in November 2018, could expose data under certain circumstances. In those cases, you'll need a firmware upgrade for the SSD; on older drives where that upgrade is not available, you can switch to software encryption using the instructions in this Microsoft Security Advisory: Guidance for configuring BitLocker to enforce software encryption.
