A few months after releasing a technical preview of Windows Search 4.0, Microsoft has released the final version of its updated desktop search software.

If you've ever tried using the search feature in Windows XP or earlier Windows operating systems, you know that it can take several long minutes to get your results. Windows Search cuts that time down to seconds by constantly indexing every file on your desktop. If you have a lot of documents and media files on your PC, that index file can eat up a few hundred megabytes or even a few gigabytes, so you'll want to make sure you've got some free hard disk space before installing Windows Search.

Several other Microsoft products including Outlook 2007, OneNote 2007 and Windows Vista use Windows Search technology. But you can also download and install the standalone search client for any Windows XP, Vista, or Server 2003 system.

Windows Search 4.0 includes a number of bug fixes, allows you to index encrypted files, and provides search results faster than previous versions. If you're looking for a different free desktop search application, you might want to check out Google Desktop or Copernic Desktop Search.
