What’s Windows Search?

Windows Search 4.0 lets you perform an instant search of your computer. Windows Search 4.0 helps you find and preview documents, e-mail messages, music files, photos, and other items on the computer.

The search engine in Windows Search 4.0 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 in a particular program.

Windows Search v4.0 was released a couple of days ago. If you have installed it before on XP or using a Windows Vista, then you should upgrade to the latest version.

Windows Search 4.0 includes the following improvements (taken from Microsoft’s page):

Support for indexing encrypted documents of local file systems
Reduced affect on Microsoft Exchange when you index e-mail in online mode, and there is no local cache (.ost)
Support for indexing online delegate mailboxes
Support for client-to-client remote query to shared indexed locations
Improved indexing performance
Faster previewer updates for Windows XP
Per-user Group Policy settings
Windows software updates for Watson errors
Support for the following new enterprise Group Policy objects:

If you own Windows Vista, Windows Search is built in into the system (version 3.0). So it’s still worthy of an upgrade.
