Microsoft has released a preview of the engine behind the upcoming Windows Desktop Search 3.0. However, the update is intended for users of Microsoft Office Outlook 2007 and Microsoft OneNote 2007. Existing users of Windows Desktop Search 2.0 should not upgrade unless you are using these applications. Still, it shouldn’t be too long before a beta for normal WDS users is released. Personally, I hope they’ll be adding more interactive options for the quick preview search window performed from the taskbar. An improvement in speed when it comes to search results couldn’t hurt either but WDS is still (approximately) one billion times faster than the search tool built into Windows. (Shudder.) WDS also continues to, in my opinion, provide better Windows/Office integration than even the latest desktop search offering from Google.
