Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. This article for the IT professional explains how BitLocker features can be used to protect your data through drive encryption. BitLocker provides full volume encryption FVE for operating system volumes, and fixed and removable data drives. To support fully encrypted operating system drives, BitLocker uses an unencrypted system partition for the files required to boot, decrypt, and load the operating system.
This volume is automatically created during a new installation of both client and server operating systems. If the drive was prepared as a single contiguous space, BitLocker requires a new volume to hold the boot files. For more info about using this tool, see Bdehdcfg in the Command-Line Reference. The BitLocker control panel supports encrypting operating system, fixed data, and removable data volumes. The BitLocker control panel will organize available drives in the appropriate category based on how the device reports itself to Windows.
Only formatted volumes with assigned drive letters will appear properly in windows 10 enterprise bitlocker requirements free BitLocker control panel applet. BitLocker Drive Encryption Wizard options vary based on volume type operating system volume or data volume. When the BitLocker Drive Encryption Wizard launches, it verifies the computer meets the BitLocker system requirements for encrypting an operating system volume. By default, the system requirements are:. A TPM isn't required for BitLocker; however, only a computer with a TPM can provide the additional security of pre-startup windows 10 enterprise bitlocker requirements free integrity verification and multifactor authentication.
The firmware must be able to read from a USB flash drive during startup. For either firmware, the system drive partition must be at least megabytes MB and set as the active partition. Hardware encrypted drive prerequisites optional To use a hardware encrypted drive as the boot drive, the drive must be in the uninitialized state and in the security inactive state.
In addition, the system must always boot with native UEFI version 2. Upon passing the initial configuration, users are required to enter a password for the volume. If the volume doesn't pass the initial configuration for BitLocker, the user is presented with an error dialog describing the appropriate actions to be taken. Once a strong password has been created for the volume, a recovery key will be generated. A BitLocker recovery key is a special key that you can create when you turn on BitLocker Drive Encryption for the first time on each drive that you encrypt.
Windows 10 enterprise bitlocker requirements free can use the recovery key to gain access to your computer if the drive that Windows is windows 10 enterprise bitlocker requirements free on the operating system drive is encrypted using BitLocker Drive Encryption and BitLocker detects a condition that prevents it from unlocking the drive when the computer is starting up.
A recovery key can also be used to gain access to your files and folders on a removable data drive such as an external hard drive or USB flash drive that is encrypted using BitLocker Windows 10 enterprise bitlocker requirements free Go, if for some reason you forget the password or your computer can't access the drive. You should store the recovery key by printing it, saving it on removable media, or saving it as a file in a network folder or on your OneDrive, or on another drive of your computer that you aren't encrypting.
You can't save the recovery key to the root directory of a non-removable drive and can't be stored on the encrypted volume. You can't save the recovery key for a removable data drive such as a USB flash drive on removable media. Ideally, you should store the recovery key separate from your computer. After you create a recovery key, you can use the BitLocker control panel to make additional copies.
It's recommended that drives with little windows 10 enterprise bitlocker requirements free no data use the used disk space only encryption option and that drives with data or an operating system use the encrypt entire drive option. Deleted files appear as free space to the file system, which isn't encrypted by used disk space only. Until they are wiped or overwritten, deleted files hold information that could be recovered with common data forensic tools.
Selecting an encryption type and choosing Next will give the user the option of running a BitLocker system check selected by default which will ensure that BitLocker can properly access the recovery and encryption keys before the volume encryption begins. We recommend running this system check before starting the encryption process. If the system check isn't run and a problem is encountered when читать operating system attempts to start, the user will need to provide the recovery key to start Windows.
After completing the system check if selectedthe BitLocker Drive Encryption Wizard restarts the computer to begin encryption. Upon reboot, users are required to enter the password chosen to boot into the operating system volume. Users can check encryption status by checking the system notification area or the BitLocker control panel. Until encryption is completed, the only available options for managing BitLocker involve manipulation of the password protecting the operating system volume, backing up the windows 10 enterprise bitlocker requirements free key, and turning off BitLocker.
Encrypting data volumes using the BitLocker control panel interface works in a similar fashion to encryption of the operating system volumes. Unlike for operating system volumes, data volumes aren't required to pass any configuration tests for the wizard to proceed.
Upon launching the wizard, a choice of authentication methods to unlock the drive appears. The available options are password and smart card and automatically unlock this drive on this computer. Disabled by default, the latter option will unlock the data volume without user input when the operating system volume is unlocked. After selecting the desired authentication method and choosing Nextthe wizard presents options for storage of the recovery key.
These options are the same as for operating system volumes. With the recovery key saved, selecting Next in the wizard will show available options for encryption. These options are sony vegas pro freetrial bit free same as for operating system volumes; used disk space only and full drive encryption.
If the volume being encrypted is new or empty, it's recommended that used space only encryption is selected.
With an encryption method chosen, a final confirmation screen is displayed before the encryption process begins. Selecting Start encrypting begins encryption. There's a new option for storing the BitLocker recovery key using the OneDrive. This option requires that computers aren't members of a domain and that the user is using a Microsoft Account. Local accounts don't give the option to use OneDrive. Using the OneDrive option is the default, recommended recovery key storage method for computers that aren't joined to a domain.
Users can verify whether the recovery key was saved properly by checking their OneDrive for the BitLocker folder which is created automatically windows 10 enterprise bitlocker requirements free the save process. The folder will contain two files, a readme. For users storing more than one recovery password on their OneDrive, they can identify the required recovery key by looking at the file name.
The recovery key ID is appended to the end of the file name. This option is available on client computers by default. On servers, you must first install the BitLocker and Desktop-Experience features for this option to be available. After selecting Turn on BitLockerthe wizard works exactly as it does when launched using the BitLocker control panel.
The following table shows the compatibility matrix for systems that have been BitLocker-enabled and then presented to a different version нажмите чтобы узнать больше Windows. Table 1: Cross compatibility for Windows 11, Windows 10, Windows 8. Manage-bde is a command-line utility that can be used for scripting BitLocker windows 10 enterprise bitlocker requirements free. Manage-bde offers additional options not displayed in the Windows 10 enterprise bitlocker requirements free control panel.
For a complete list of the options, see Manage-bde. Manage-bde offers a multitude of wider options for configuring BitLocker. So using the command syntax may require care and possibly later customization by the user.
For example, using just the manage-bde -on command on a data volume will fully encrypt the volume without any authenticating protectors. A volume encrypted in this manner still requires user interaction to turn on BitLocker protection, even though the command successfully completed because an нажмите чтобы перейти method needs to be added to the volume for it to be fully protected.
Command-line users need to determine the appropriate syntax for a given situation. The following section covers general encryption windows 10 enterprise bitlocker requirements free operating system volumes and data volumes. Listed below are examples of basic valid commands for operating system volumes. However, many environments require more secure protectors such as passwords or PIN and expect to be able to recover information with a recovery key.
A good practice when windows 10 enterprise bitlocker requirements free manage-bde is to determine the volume status on the target system. Use the following command to determine volume status:. This command returns the volumes on the target, current encryption status, and volume type operating system or data for each volume. Using this information, users can determine the best encryption method for their environment. To properly windows 10 enterprise bitlocker requirements free BitLocker for the operating system volume, you'll need to use a USB flash drive as a startup key to boot in this example, the drive letter E.
You would first create the startup key needed for BitLocker using the —protectors option and save it to the USB drive on E: and then begin the encryption process. You'll need to reboot the computer when prompted to complete the encryption process. It's possible to encrypt the operating system volume without any defined protectors by using manage-bde.
Use this command:. This will encrypt the drive using the TPM as the protector. If users are unsure of the protector for a volume, they can use the -protectors option in manage-bde to list this information by executing the following command:. Another example is a user on a non-TPM hardware who wishes to add a password and SID-based protector to the operating system volume. In this instance, the user adds the protectors first. This is done with the command:.
This command requires the user to enter and then confirm the password protectors before adding them to the volume. With the protectors enabled on the volume, the user just needs to turn BitLocker on. Data volumes use the same syntax for encryption as operating system volumes but they don't require protectors for the operation to complete. We recommend that you add at least one primary protector and a recovery protector to a data volume. A common protector for a data volume is the password protector.
In the example below, we add a password protector to the volume and turn on Привожу ссылку. Windows PowerShell cmdlets provide an alternative windows 10 enterprise bitlocker requirements free to work with BitLocker.
Using Windows PowerShell's scripting capabilities, administrators can integrate BitLocker options into existing scripts with ease. The list below displays the available BitLocker cmdlets. Similar to manage-bde, the Windows PowerShell cmdlets allow configuration beyond the options offered in the control panel.
