BitLocker is a full-volume encryption feature included with Microsoft Windows. Unfortunately, windows Home Editions don’t have BitLocker Drive Encryption (BDE). However, suppose you have a hard drive that’s already encrypted using BDE. In that case, Windows 11/10 Home Edition can use the drive if the user has the 48-digit BitLocker recovery password or the recovery key.
