Excel 2010 comes with tools that can help you manage, protect, and share your content.
* Recover previous versions You can now recover versions of files that you closed without saving. This is helpful when you forget to manually save, when you save changes that you didn't mean to save, or when you just want to revert to an earlier version of your workbook. Read more about recovering files.
* Protected view Excel 2010 includes a Protected View, so you can make more informed decisions before exposing your computer to possible vulnerabilities. By default, documents that originate from an Internet source are opened in Protected View. When this happens, you see a warning on the Message bar, along with the option to enable editing. You can control which originating sources trigger Protected View. You can also set specific file types to open in Protected View regardless of where they originate. Read more about Protected View.
* Trusted documents The trusted documents feature is designed to make it easier to open workbooks and other documents that contain active content, such as data connections or macros. Now, after you confirm that active content in a workbook is safe to enable, you don't have to repeat yourself. Excel 2010 remembers the workbooks you trust so that you can avoid being prompted each time you open the workbook.
