How to Use the New File History Feature in Windows 8
 

Jealous of your Mac OS X friends and their great Time Machine feature? Windows 8 has a new feature called File History that works much the same way, giving you an easy method to restore previous versions of your files.

If you’re a Windows 7 or Vista user, you’ve probably already read about how to use Previous Versions, and this is similar, but works a lot better. By default File History in Windows 8 takes snapshots of all files in your Libraries, Desktop, Contacts, and Favorites every hour (although this can be changed to more frequently or less frequently) and keeps the snapshots forever (this can also be changed).
