BitLockerÂ Drive Encryption is a data protection feature that integrates with the operating system and addresses the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned drives and computers.
New files are automatically encrypted when you save them to a drive encrypted by BitLocker. However, if you copy these files to another drive or a different PC not encrypted by BitLocker, the files are automatically decrypted.
You can choose to unlock BitLocker for a fixed data drive automatically if BitLocker is turned on for OS drive, or with a password or smart card.
This tutorial will show you how to turn on BitLocker to encrypt a fixed data drive in Windows 11.
