BITLOCKER ENCRYPTION FULL
Rather than paraphrasing, here’s the full description for these options: This lets you set the configuration for using removable memory or TPM with BitLocker.Ĭlick Enable to access the other options. Navigate to Computer Configuration \ Administrative Templates \ Windows Components \ BitLocker Drive Encryption \ Operating System Drivesĭouble-click Require additional authentication at startup. This launches the Local Group Policy Editor. Press Windows + R to bring up the Run dialog, type gpedit.msc and press Enter. To enable BitLocker on a system with a TPM by storing the key on a removable USB stick, follow these steps:
BITLOCKER ENCRYPTION HOW TO
In this article I’m illustrating how to do it on a standalone system. In a domain-joined computer, you will typically do that through Group Policy. To enable these options, you must configure the policy.
BITLOCKER ENCRYPTION WINDOWS 10
From that point on, the USB stick must be inserted whenever Windows 10 starts. BitLocker will create the key and store it on the USB stick. Removable storage, typically a USB memory stick, must be provided for the key. When a TPM is not available BitLocker can still work. Your administrator must set the “Allow BitLocker without a compatible TPM” option in the “Require additional authentication at startup” policy for OS volumes.

If you are using a Professional or Enterprise version of Windows 10 you can enable BitLocker through BitLocker Drive Encryption applet in Control Panel. This is normally how BitLocker is deployed, with keys stored in the TPM. When an attacker tries to steal or modify keys protected by a TPM, the TPM either destroys itself, wipes its own memory, or reduces functionality in a recovery mode. The best practice is to store the BitLocker key in a Trusted Platform Module (TPM), which is a secure system component that protects cryptographic keys and prevents tampering and unauthorized access. BitLocker has always provided a great level of data confidentiality by encrypting an entire logical drive, not just files.Īll modern encryption uses a key, and BitLocker is no different. BitLocker was first shipped as part of the Operating System Who Must Not Be Named (the predecessor of Windows 7). Encrypting files in Windows goes all the way back to the Encrypting File System (EFS) in Windows 2000. It’s fast, it runs all of my old apps (even my retro games!), and it has tons of security improvements.īitLocker Drive Encryption isn’t new to Windows 10. Windows 10 is quite an impressive operating system.
