The search engine in WDS 3.0 is a Microsoft Windows service that is also used by programs such as Microsoft Office Outlook 2007 and Microsoft Office OneNote 2007. You can use this search engine to index a program's content and to obtain instant results when you search within a particular program. WDS 3.0 supports the following installations:

•	Microsoft Windows XP Service Pack 2 (SP2) and later versions
•	Microsoft Windows Server 2003 Service Pack 1 (SP1) and later versions

You cannot install WDS 3.0 on a Microsoft Windows Vista-based computer, because WDS functionality is already built into Windows Vista.

This Beta 2 release is an update to the Beta Engine Preview release of WDS 3.0. The most noticeable improvements in the Beta 2 release include a full desktop search user interface, 64-bit support, and faster search results. The WDS 3.0 installation process will automatically upgrade WDS 2.5 and later versions of WDS. Before you install WDS 3.0, use the Add or Remove Programs tool to uninstall versions of WDS that are earlier than version 2.5.
