I wouldn't see why you would turn it off. Many new parts of Vista use an
automatic low priority mode, meaning they kick back and let you do what you
gotta do and work very slowly. Also, Search Indexer does not index your
entire PC in Vista, only a couple of user folders:
-Outlook emails (if you have them)
-Offline Files
-Start Menu
-Users, exclude Default
You can add to these. This thing works GREAT with winamp.
