Windows Search on Windows Update
Good news from the Windows Search team. In late July Windows Search 4.0 will be available on the Windows Update. For XP users available as "Optional" update and Windows Vista users will see it as a "Recommended" update.
Me, myself and I really do like this tool. Searches the hard drive and network drives pretty fast and within documents too.
