Question:
Both BitLocker and Encrypting File System (EFS) are unavailable in Windows Home editions. BitLocker encrypts entire drives while EFS allows for encryption/decryption of individual volumes, files, and folders stored in NTFS volumes. Device encryption can be utilized instead if the necessary hardware (Trusted Platform Module [TPM] enabled in BIOS/UEFI and Secure Boot enabled) is available. Only someone with permission to use the device will be able to decrypt it after it has been encrypted. To enable device encryption, you must be logged in as an administrator. To do this, go to Start => Settings => Update & Security => Device Encryption. Device encryption is unavailable on the device if the option isn't there. Launch the System Information utility as an administrator, then scroll down to Device Encryption Support to see if the hardware is compatible.
