Windows 10: Encryption software

Not a national security issue, but I have a couple of files that I'd like to encryption so casual users, like a friend a my party who wants to search the web for something, would not see it accidentally.

Preferably something free and easy to use. Any suggestions?

 

Software encryption

read this:
The Encrypting File System (EFS) is a file system driver with filesystem-level encryption available in Microsoft Windows (2000 and later) operating systems, except Windows XP Home Edition, Windows Vista Basic, and Windows Vista Home Premium. The technology transparently allows files to be encrypted on NTFS file systems to protect confidential data from attackers with physical access to the computer.

User authentication and access control lists can protect files from unauthorized access while the operating system is running, but are easily circumvented if an attacker gains physical access to the computer. One solution is to store the files encrypted on the disks of the computer. EFS does this using public key cryptography, and aims to ensure that decrypting the files is in theory impossible without the correct key. However, EFS is in practice susceptible to brute-force attacks against the user account passwords. In other words, encryption of files is only as strong as the password to unlock the decryption key.
