This configuration helps protect the operating system and the information in the encrypted drive. BitLocker supports TPM version 1. BitLocker support for TPM 2. TPM 2. Devices with TPM 2. For added security Enable the Secure Boot feature.
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. 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. 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.
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.

In the Device Manager window that opens look for "Security Devices" and upon expanding that you should see "Trusted Platform Module" followed by a version number.
You could right click it to see if the settings for it allow you to enable it. If yes, you would simply use the options in the right pane of that window to prepare and enable it. The TPM may exist and yet the above two methods may fail to show it. Reboot the computer and access the BIOS settings. The method to access BIOS settings varies across computers.
It typically involves pressing a specific key or key combination during the computer startup. This introduces a minor inconvenience every time you restart your computer. Also, if the PC received updates overnight and the update required it to be restarted, the computer will not be able to perform the restart until you arrive and enter the startup password.
Other than this, BitLocker will behave exactly as with a TPM, and you will not notice it when using the computer after the startup. To do this,. Make sure to save your recovery keys in a safe place. You should enable BitLocker on all storage drives - both internal and external. Simply repeat the above steps on each data drive on your computer, listed under This PC. We do not recommend using external drives to the extent possible because even after encryption, they remain difficult to track.
It is not easy to ensure that every such drive is encrypted, is not accidentally decrypted, and that you know the password or recovery key for each. If you used such USB drives to move data among PCs consider using a free secure document portal to move data. If you use such a drive for backup, consider a cloud based backup service with encryption, such as CrashPlan or Carbonite. Both allow using an encryption key managed by them, or optionally known only to you.
If you must use an external disk for backup, say in addition to the cloud backup, do enable BitLocker on it. For convenience, you may set it to unlock automatically when attached to this specific computer. This way you do not need to type in the BitLocker password every time to unlock the disk. However, be aware that should you actually need to use the backup, which usually means connecting the backup drive to a different PC, you will need either the BitLocker password or recovery key.
So do save them somewhere safe in your Microsoft account or a free secure document portal.

A physically-present attacker might attempt to install a bootkit or rootkit-like piece of software into the boot chain in an attempt to steal the BitLocker keys. These files are secured on an encrypted volume by default when BitLocker is enabled on OS drives. It also blocks automatic or manual attempts to move the paging file.
Enable secure boot and mandatorily prompt a password to change BIOS settings. Physical access may be limited by a form factor that doesn't expose buses and memory. For example, there are no external DMA-capable ports, no exposed screws to open the chassis, and memory is soldered to the mainboard. Targeted attack with plenty of time; this attacker will open the case, will solder, and will use sophisticated hardware or software.
Disable Standby power management and shut down or hibernate the device before it leaves the control of an authorized user. This can be set using Group Policy:. For some systems, bypassing TPM-only may require opening the case, and may require soldering, but could possibly be done for a reasonable cost. Data encryption is a critical factor in keeping your data safe. If you lost the data from BitLocker encrypted drive by a mistake, iBoysoft Data Recovery is a professional data recovery software that can help you a lot.
Amanda is one of the main columnists at iBoysoft. She loves exploring new technologies, focusing on macOS, Windows OS, data recovery, data security, disk management, and other tech-related issues.
She takes delight in providing technical and informative articles to help people out of problems and get the utmost out of their devices. The following example shows how to enable BitLocker on an operating system drive using only the TPM protector:.
In the example below, adds one additional protector, the StartupKey protector and chooses to skip the BitLocker hardware test. In this example, encryption starts immediately without the need for a reboot.
Data volume encryption using Windows PowerShell is the same as for operating system volumes. Add the desired protectors prior to encrypting the volume. This protector can be added to both operating system and data volumes, although it does not unlock operating system volumes in the pre-boot environment. The protector requires the SID for the domain account or group to link with the protector.
BitLocker can protect a cluster-aware disk by adding a SID-based protector for the Cluster Name Object CNO that lets the disk properly fail over to and be unlocked by any member computer of the cluster. For users who wish to use the SID for the account or group, the first step is to determine the SID associated with the account. This does not require the use of additional features.

Note After the encryption is completed, the USB startup key must be inserted before the operating system can be started. Tip If you are not backing up recovery information to AD DS or if you want to save key packages alternatively, you can use the command manage-bde -KeyPackage to generate a key package for a volume. Here's how to check System Information.
To prevent devices from starting recovery unnecessarily, follow these guidelines to apply firmware updates:. The firmware update should require the device to suspend Bitlocker only for a short time, and the device should restart as soon as possible. To add a bus or device to the allowed list, you need to add a value to a registry key. To do this, you need to take the ownership of the AllowedBuses registry key first.
Follow these steps:. Click Advanced , click the Change link in the Owner field, enter your user account name, click Check Names, and then click OK three times to close all permission dialogs. Then click OK. OEMs can choose to disable device encryption and instead implement their own encryption technology on a device.
Triage is much simpler when you know the following pieces of information about the device under test:. As for how to do that, please refer to the following steps:. Step 3: Highlight Operating System Drives and then double-click Require additional authentication at startup policy on the right pane. Then, click the Apply and the OK button to save changes.
Then, right click the operating system drive that you want to encrypt and choose Turn on BitLocker. In this step, I choose Enter a password. The former option allows you to unlock the operating system drive at startup with a connected USB flash drive saving startup key. The latter option allows you to unlock the operating system drive with a password. Step 7: Set a password and then choose how to back up the BitLocker recovery key.
