Microsoft Excel, Word, and PowerPoint 2010 have a new feature that allows you to recover unsaved documents, even ones that you never saved. This expands on the Autosave feature that was available for years, but unlike earlier versions of MS Office, the automated backups are not deleted when you close your Office host. Additionally, multiple versions of your file are maintained, so that you can return to an earlier version of your document.
