Windows Search 4.0 will begin automatic updates using Windows Update within the next week or so to Windows Vista, but will be an optional update for Windows XP users.
The new version will update the indexes, Search will release most of the requested resources and slow down the indexing process as soon as it detects mouse or keyboard activity, or when another application requires computer resources.
Details of the update are posted on TechNet at Reminder – Windows Search 4 coming to WU soon…
