In Windows 8 you can do this by accessing the Charms menu, clicking 'Search', and typing the name.  In other words, be careful or you will find yourself locked out of your own files.Īlthough we are using Windows 8 here, the steps are the same if you are running either Windows XP or Windows 7, so don't feel left out of the fun if you are on an older OS. Although other users on the same computer might be able to see your files, they will be unable to open them, even if they are running as Administrator. Using the service is fairly simple, but user beware: files can ONLY be decrypted by using the Windows login that encrypted the file.  However, every version of Windows since XP has simple file and folder encryption called Encrypted File Service or EFS. For those using Windows 8 there is built-in file encryption, called Bit-Locker, available, but only if you are using the Pro or Enterprise version of the operating system.
