Which Windows 10 feature enhances full disk encryption?

BitLocker is a full disk encryption feature included in Windows 10 that provides data protection by encrypting the entire drive. This ensures that all data on the drive is protected from unauthorized access, particularly in cases where a device is lost or stolen. BitLocker uses the Advanced Encryption Standard (AES) to encrypt data, helping to safeguard information by making it unreadable to anyone who does not have the proper decryption key.

Additionally, BitLocker integrates with the Trusted Platform Module (TPM) hardware, which enhances security by binding the encryption keys to the device. This means that even if someone tries to access the encrypted data on a different system, they will not be able to decrypt the information without the TPM or the recovery key.

In contrast, AppLocker is used for application whitelisting, helping administrators control which applications can run on a device. Cortana is a digital assistant that assists users with tasks and information but does not directly relate to disk encryption. Windows Defender is an antivirus tool providing protection against malware but is not specifically focused on disk encryption. These features serve different functions within the Windows operating system and do not enhance full disk encryption like BitLocker does.
