One welcome feature in the Microsoft Word Web App is document versioning. The app automatically saves earlier drafts of a document. That makes it easy to see how a document has evolved over time. Better yet, you can easily restore an older version of a document.
To access earlier versions of a document, follow these easy steps:
1. Sign in to your Windows Live account
2. Click Office>>Your Documents
3. Hold your mouse over the document you'd like to see versions of
4. Click More and select Version history
You will see a full view of the latest version of the document. At the left of the window, you will see earlier versions of the document. To view a version, simply click the corresponding date in the list of document versions. To restore a version, open it and click the Restore link under the version date.
