BitLocker encrypts your entire drive to protect data from unauthorized access. This guide walks through enabling BitLocker on Windows 10 and 11 Pro editions.

Requirements

A TPM 1.2 or later chip is required (or you can enable software-based encryption via Group Policy).

Enable BitLocker

Open Control Panel > System and Security > BitLocker Drive Encryption and click Turn on BitLocker next to your drive.

Save Your Recovery Key

Store the recovery key in a safe place — without it you cannot access your data if you forget the PIN.
