How does BitLocker work?
How BitLocker works with operating system drives
You can use BitLocker to mitigate unauthorized data access on lost or stolen computers by encrypting all user files and system files on the operating system drive, including the swap files and hibernation files, and checking the integrity of early boot components and boot configuration data.
How BitLocker works with fixed and removable data drives
You can use BitLocker to encrypt the entire contents of a data drive. You can use Group Policy to require that BitLocker be enabled on a drive before the computer can write data to the drive. BitLocker can be configured with a variety of unlock methods for data drives, and a data drive supports multiple unlock methods.

Does BitLocker support multifactor authentication?
Yes, BitLocker supports multifactor authentication for operating system drives. If you enable BitLocker on a computer that has a TPM version 1.2 or later, you can use additional forms of authentication with the TPM protection.
What are the BitLocker hardware and software requirements?
For requirements, see System requirements.
Note
Dynamic disks are not supported by BitLocker. Dynamic data volumes will not be displayed in the Control Panel. Although the operating system volume will always be displayed in the Control Panel, regardless of whether it is a Dynamic disk, if it is a dynamic disk it cannot be protected by BitLocker.
Why are two partitions required? Why does the system drive have to be so large?
Minimoog history. Two partitions are required to run BitLocker because pre-startup authentication and system integrity verification must occur on a separate partition from the encrypted operating system drive. This configuration helps protect the operating system and the information in the encrypted drive.
Which Trusted Platform Modules (TPMs) does BitLocker support?
BitLocker supports TPM version 1.2 or higher. BitLocker support for TPM 2.0 requires Unified Extensible Firmware Interface (UEFI) for the device.
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.
How can I tell if a TPM is on my computer?
Beginning with Windows 10, version 1803, you can check TPM status in Windows Defender Security Center > Device Security > Security processor details. In previous versions of Windows, open the TPM MMC console (tpm.msc) and look under the Status heading.
Can I use BitLocker on an operating system drive without a TPM?
Yes, you can enable BitLocker on an operating system drive without a TPM version 1.2 or higher, if the BIOS or UEFI firmware has the ability to read from a USB flash drive in the boot environment. This is because BitLocker will not unlock the protected drive until BitLocker's own volume master key is first released by either the computer's TPM or by a USB flash drive containing the BitLocker startup key for that computer. However, computers without TPMs will not be able to use the system integrity verification that BitLocker can also provide.To help determine whether a computer can read from a USB device during the boot process, use the BitLocker system check as part of the BitLocker setup process. This system check performs tests to confirm that the computer can properly read from the USB devices at the appropriate time and that the computer meets other BitLocker requirements.
How do I obtain BIOS support for the TPM on my computer?
Contact the computer manufacturer to request a Trusted Computing Group (TCG)-compliant BIOS or UEFI boot firmware that meets the following requirements:
- It is compliant with the TCG standards for a client computer.
- It has a secure update mechanism to help prevent a malicious BIOS or boot firmware from being installed on the computer.
What credentials are required to use BitLocker?
To turn on, turn off, or change configurations of BitLocker on operating system and fixed data drives, membership in the local Administrators group is required. Standard users can turn on, turn off, or change configurations of BitLocker on removable data drives.
What is the recommended boot order for computers that are going to be BitLocker-protected?
You should configure the startup options of your computer to have the hard disk drive first in the boot order, before any other drives such as CD/DVD drives or USB drives. If the hard disk is not first and you typically boot from hard disk, then a boot order change may be detected or assumed when removable media is found during boot. The boot order typically affects the system measurement that is verified by BitLocker and a change in boot order will cause you to be prompted for your BitLocker recovery key. For the same reason, if you have a laptop with a docking station, ensure that the hard disk drive is first in the boot order both when docked and undocked.
Solved: BitLocker is Missing from Control Panel in Windows 10As many important files are stored in the USB drive, you may consider to encrypt it with BitLocker in your Windows 10 laptop. However, you might find that where BitLocker feature can be enabled normally. At that time, you need to check that if the installed Windows 10 is the edition (Windows 10 Pro or Windows 10 Enterprise and Education) which supports BitLocker feature first.
If it is, you can try the following way to recover the missing BitLocker in control panel.Step 1: Enter ' services.msc' in the search box of the task bar and click the services.msc option.Step 2: In the pop-out Services window, choose ' BitLocker Drive Encryption Service' option in the right panel.Step 3: Tap ' Start' button under Service status in the BitLocker Drive Encryption Service Properties box.Note: After tapping Start button, a start-service window will be popped out.Step 4: Select ' Automatic' option in the drop-down menu of Startup type. Then click ' OK' to save the change and BitLocker Drive Encryption option will be shown in the control panel again.Tips: If the way above can't solve the problem for you, there might be something wrong in the system and you could try to reinstall it to recover BitLocker feature in control panel.Related Articles:.
