In contrast, encrypting only used space on a brand-new volume can significantly decrease deployment time without the security risk because all new data will be encrypted as it’s written to the disk. SEDs have been available for years, but Microsoft couldn’t support their use with some earlier versions of Windows because the drives lacked important key management features.

Microsoft worked with storage vendors to improve the hardware capabilities, and now BitLocker supports the next generation of SEDs, which are called encrypted hard drives. Encrypted hard drives provide onboard cryptographic capabilities to encrypt data on drives. This feature improves both drive and system performance by offloading cryptographic calculations from the PC’s processor to the drive itself. Data is rapidly encrypted by the drive by using dedicated, purpose-built hardware.

If planning to use whole-drive encryption with Windows 11 or Windows 10, Microsoft recommends researching hard drive manufacturers and models to determine whether any of their encrypted hard drives meet the security and budget requirements. For more information about encrypted hard drives, see Encrypted hard drive. An effective implementation of information protection, like most security controls, considers usability and security. Users typically prefer a simple security experience.

In fact, the more transparent a security solution becomes, the more likely users are to conform to it. It’s crucial that organizations protect information on their PCs regardless of the state of the computer or the intent of users.

This protection shouldn’t be cumbersome to users. One undesirable and previously commonplace situation is when the user is prompted for input during preboot, and then again during Windows sign-in. Challenging users for input more than once should be avoided. Windows 11 and Windows 10 can enable a true SSO experience from the preboot environment on modern devices and in some cases even on older devices when robust information protection configurations are in place.

The TPM in isolation is able to securely protect the BitLocker encryption key while it is at rest, and it can securely unlock the operating system drive. When the key is in use and thus in memory, a combination of hardware and Windows capabilities can secure the key and prevent unauthorized access through cold-boot attacks. Although other countermeasures like PIN-based unlock are available, they aren’t as user-friendly; depending on the devices’ configuration they may not offer additional security when it comes to key protection.

For more information, see BitLocker Countermeasures. Such a PIN requirement can prevent an attacker who has physical access to a PC from even getting to the Windows sign-in, which makes it almost impossible for the attacker to access or modify user data and system files. Requiring a PIN at startup is a useful security feature because it acts as a second authentication factor.

However, this configuration comes with some costs. You must be an administrator to perform these procedures. For more information about setting this policy, see System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing. When a computer transitions to Sleep, open programs and documents are persisted in memory. This might lead to conditions where data security is compromised. However, when a computer hibernates the drive is locked, and when it resumes from hibernation the drive is unlocked, which means that users will need to provide a PIN or a startup key if using multifactor authentication with BitLocker.

Therefore, organizations that use BitLocker may want to use Hibernate instead of Sleep for improved security. This setting doesn’t have an impact on TPM-only mode, because it provides a transparent user experience at startup and when resuming from the Hibernate states. The scope of the values can be specific to the version of the operating system.

PCR 7 measures the state of Secure Boot. Secure Boot ensures that the computer’s preboot environment loads only firmware that is digitally signed by authorized software publishers. PCR 7 measurements indicate whether Secure Boot is on and which keys are trusted on the platform.

This reduces the likelihood of BitLocker starting in recovery mode as a result of firmware and image updates, and it provides you with greater flexibility to manage the preboot configuration.

With this policy setting, you can control whether a BitLocker-protected computer that is connected to a trusted local area network and joined to a domain can create and use network key protectors on TPM-enabled computers to automatically unlock the operating system drive when the computer is started.

With this policy setting, you can configure whether BitLocker requires additional authentication each time the computer starts and whether you are using BitLocker with a Trusted Platform Module TPM. If one authentication method is required, the other methods can’t be allowed. Users can configure advanced startup options in the BitLocker Setup Wizard.

Users can configure only basic options on computers with a TPM. Existing drives that were protected by using standard startup PINs aren’t affected. The startup PIN must have a minimum length of four digits, and it can have a maximum length of 20 digits. By default, the minimum PIN length is 6. You can require that startup PINs set by users must have a minimum length you choose that is between 4 and 20 digits.

Users can configure a startup PIN of any length between 6 and 20 digits. DMA is available on hot pluggable PCI devices if the device is turned on, regardless of whether a user is signed in.

With this policy setting, you can configure whether standard users are allowed to change the PIN or password used to protect the operating system drive. With this policy setting, you can specify the constraints for passwords that are used to unlock operating system drives that are protected with BitLocker. Passwords can’t be used if FIPS-compliance is enabled. Users can configure a password that meets the requirements you define.

The default length constraint of eight characters will apply to operating system drive passwords and no complexity checks will occur. With this policy setting, you can control whether the BitLocker Setup Wizard on computers running Windows Vista or Windows Server can set up an additional authentication method that is required each time the computer starts.

If you choose to require an additional authentication method, other authentication methods can’t be allowed. The BitLocker Setup Wizard displays the page that allows the user to configure advanced startup options for BitLocker. You can further configure setting options for computers with or without a TPM.

In this basic wizard, no additional startup key or startup PIN can be configured. With this policy setting, you can specify whether smart cards can be used to authenticate user access to the BitLocker-protected fixed data drives on a computer. Smart cards can be used to authenticate user access to the drive. You can require smart card authentication by selecting the Require use of smart cards on fixed data drives check box. Users can’t use smart cards to authenticate their access to BitLocker-protected fixed data drives.

Smart cards can be used to authenticate user access to a BitLocker-protected drive. With this policy setting, you can specify whether a password is required to unlock BitLocker-protected fixed data drives. To require the use of a password, select Require password for fixed data drive. To enforce complexity requirements on the password, select Require complexity. Passwords are supported with the default settings, which don’t include password complexity requirements and require only eight characters.

With this policy setting, you can specify whether smart cards can be used to authenticate user access to BitLocker-protected removable data drives on a computer. You can require smart card authentication by selecting the Require use of smart cards on removable data drives check box. Users aren’t allowed to use smart cards to authenticate their access to BitLocker-protected removable data drives.

Smart cards are available to authenticate user access to a BitLocker-protected removable data drive. With this policy setting, you can specify whether a password is required to unlock BitLocker-protected removable data drives.

To require the use of a password, select Require password for removable data drive. With this policy setting, you can associate an object identifier from a smart card certificate to a BitLocker-protected drive.

The object identifier that is specified in the Object identifier setting must match the object identifier in the smart card certificate. BitLocker manages and updates data recovery agents only when the identification field on the drive matches the value that is configured in the identification field. In a similar manner, BitLocker updates the BitLocker To Go Reader only when the identification field’s value on the drive matches the value that is configured for the identification field.

The allowed identification field is used in combination with the Deny write access to removable drives not protected by BitLocker policy setting to help control the use of removable drives in an organization. It’s a comma-separated list of identification fields from an internal organization or external organizations. The identification fields on existing drives can be configured by using the Manage-bde command-line tool. When a BitLocker-protected drive is mounted on another BitLocker-enabled computer, the identification field and the allowed identification field are used to determine whether the drive is from an external organization.

Multiple values separated by commas can be entered in the identification and allowed identification fields. The identification field can be any value upto characters. This policy setting is used to control whether the computer’s memory will be overwritten the next time the computer is restarted.

BitLocker secrets include key material that is used to encrypt data. This policy setting applies only when BitLocker protection is enabled. A platform validation profile consists of a set of PCR indices that range from 0 to The default platform validation profile secures the encryption key against changes to the following PCRs:.

Changing from the default platform validation profile affects the security and manageability of a computer. BitLocker’s sensitivity to platform modifications malicious or authorized is increased or decreased depending on inclusion or exclusion respectively of the PCRs. This policy setting determines what values the TPM measures when it validates early boot components before unlocking a drive on a computer running Windows Vista, Windows Server , or Windows 7.

This policy setting determines what values the TPM measures when it validates early boot components before unlocking an operating system drive on a computer with native UEFI firmware configurations. This group policy setting only applies to computers with a native UEFI firmware configuration.

A platform validation data profile consists of the values in a set of Platform Configuration Register PCR indices that range from 0 to For more information about the recovery process, see the BitLocker recovery guide.

A platform validation uses the data in the platform validation profile, which consists of a set of Platform Configuration Register PCR indices that range from 0 to The setting that controls boot debugging 0x is always validated, and it has no effect if it’s included in the inclusion or the exclusion list.

The use of a recovery key is permitted. This policy must be enabled before any encryption key is generated for BitLocker. When this policy is enabled, BitLocker prevents creating or using recovery passwords, so recovery keys should be used instead. The optional recovery key can be saved to a USB drive.

Only administrators can perform these procedures. For more information about setting this policy, see System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing. PCs default power settings for a computer will cause the computer to enter Sleep mode frequently to conserve power when idle and to help extend the system’s battery life.

When a computer transitions to Sleep, open programs and documents are persisted in memory. Not needing to reauthenticate when resuming from Sleep might lead to conditions where data security is compromised. However, when a computer hibernates the drive is locked, and when it resumes from hibernation the drive is unlocked, which means that users will need to provide a PIN or a startup key if using multifactor authentication with BitLocker.

Therefore, organizations that use BitLocker may want to use Hibernate instead of Sleep for improved security. This setting doesn’t have an impact on TPM-only mode, because it provides a transparent user experience at startup and when resuming from the Hibernate states.
