You have been tasked with setting up encryption for a Windows computer. What tool should you use to encrypt several folders?

The correct choice for encrypting several folders on a Windows computer is the Encrypting File System (EFS). EFS is a feature built into the Windows operating system that allows users to encrypt individual files and folders. It provides a straightforward way to protect sensitive information at the file system level, ensuring that only the user who encrypted the files can access them unless they have the appropriate permissions.

Using EFS, you can select specific folders or files to encrypt, providing flexibility in managing sensitive data. Once encrypted, these files will remain secure even if they are moved or transferred, as long as the encryption key is available only to the user who encrypted them.

In contrast, BitLocker is a full-disk encryption feature that encrypts the entire drive rather than individual folders. TPM (Trusted Platform Module) is a hardware component that enhances security features, particularly for BitLocker, but is not a tool for encrypting folders. Administrative shares are hidden network shares on a Windows system used for administrative purposes and do not provide encryption functionality.
