Documents created by Office 2007 and later use the Open Office XML document specification. This format has a JPEG thumbnail embedded in them where applicable (e.g. Word and PowerPoint documents). Windows 7 simply displays this image at the status area of Windows Explorer.

As Windows Explorer has the ZIP algorithm built in, it is a trivial matter to extract the thumbnails from supported documents.
