WFS is not available on Vista Home or Vista Home Premium.

WFS is available in Windows Vista Ultimate and as an optional component in Windows Vista Enterprise. Even though this can be used for most types of documents, WFS is optimized for scanning, viewing and storing text documents. WFS supports one-click scanning of documents from locally connected scanners, network-connected scanners and multifunction devices. Without a fax modem, users can email scanned documents and forward faxes as email attachments from their computer.

With Windows Fax and Scan users with computers that have fax modems can send and receive faxes, and fax scanned documents.
