File History is a built-in tool that was first introduced in Windows 8 and it allows you to recover files you might have accidentally deleted, or restore a modified document to an earlier version.
To use it, you’ll need an external hard drive or a large capacity USB flash drive. You can set it up to use a network location, too. File History will automatically back up Favorites, Contacts, Desktop items, and more.
File History is turned off by default. To turn on and Configure File History, type: file history into the search box and hit Enter or select it from the results at the top.
