Which technology should you use to encrypt the entire hard drive, including startup files while setting up a Windows 11 Pro machine?

You can utilize drive encryption to protect files, including those required for startup and logon, with BitLocker Drive Encryption. Only Windows Pro and higher editions come with this. To prevent unauthorized access to the files stored on removable drives, BitLocker To Go offers the same encryption technology. Despite being able to encrypt volumes, files, and folders, EFS (Encrypting File System) cannot encrypt the entire drive.
