WDS 3.01 Administrator's Guide

Applies To: Windows Server 2008

Windows Desktop Search (WDS) 3.01 is a minor update to WDS 3.0 that adds support for indexing UNC files, additional support for enterprise deployment, and stability improvements. WDS 3.01 installs on Windows XP and Window Server 2003, but is not needed for Windows Vista since the WDS component is already included in Vista. The search engine in WDS 3.01 is a Windows service that is also used by applications such as Microsoft Office Outlook 2007 and OneNote 2007 to index application content and deliver instant results when searching within those applications.

While the indexing engine that is part of WDS 3.0 and later is already part of Windows Vista, there are some differences, as described in the following table.

Feature Windows XP Windows Server 2003 Windows Vista

Filters and protocol handlers



Fast desktop search



Live icons



File tagging



Search folders



Advanced navigation



Index offline or cached files



Filters and protocol handlers are components the indexer uses to access and index files and other data stores like e-mail. Windows ships with a number of default filters and protocol handlers. All of the filters and protocol handlers that work with WDS 3.x on Windows XP also work with Windows Vista.

There are some differences in policies that apply to WDS on Windows XP versus Windows Vista. These differences are called out in the WDS Group Policy section of this guide.
