On Windows 11, BitLocker adds an extra layer of security with encryption to protect your device and files from unauthorized access. When using encryption, the feature scrambles the data on the drive to make it unreadable for anyone without the correct decryption key (your account password).

The BitLocker security feature is available on Windows 11 Pro, Enterprise, and Education editions. However, on Windows 11 Home, you can use "device encryption," a limited version of BitLocker. It works identically to the full version but without many advanced management settings and capabilities, such as "BitLocker To Go." Also, when using device encryption, all the drives will encrypt automatically, while the full version of BitLocker allows you to choose the storage using encryption.

This guide will walk you through the steps to set up device encryption with BitLocker on your computer.
