This tutorial details how to enable BitLocker drive encryption in Windows 10. One of Windows’ most important security features, BitLocker drive encryption protects your important data by encrypting the entire disk volumes it is stored on. It uses a specialized Encrypting File System to achieve this. As the latest and greatest version of Microsoft’s line of operating systems, Windows 10 features an improved version of BitLocker, with enhanced data encryption abilities. You can easily enable BitLocker drive encryption for some (or all) of your disk drive partitions, using Windows 10. The encrypted partitions (and the data stored on them) is secured against all kinds of data loss and threats. Let’s dig in deeper, and see how you can enable BitLocker drive encryption in Windows 10.

What Exactly Is BitLocker?

The detailed explanation of what BitLocker is pretty complicated and as such, the way it works to do what it does too, is verbose enough to warrant another article. However, at a basic level, BitLocker can be explained as a built in encryption feature of Windows that secures your data against all kinds of threats by encrypting the entire disk volumes it is stored on. It uses AES-256 encryption algorithm in Cipher Block Chaining (CBC) mode to do this. This, combined with an Encrypting File System (EFS) and a dedicated Trusted Platform Module (TPM) chip provide your valuable digital data some really high quality protection.
