Windows Vista works in the background to automatically index all the files in the Start Menu, user profile folders and files setup for offline access by default. If you have many files in these locations and the files change often, the indexing service may slow down your system's performance. Unlike Windows XP, Vista now allows you to easily tweak the indexing service by following these steps:
1. Click on the Start Button and select 'Indexing Options' 2. Click 'Enter' and the Indexing Options should appear 3. Click on the 'Modify button', then 'Show all locations' 4. Scroll through the tree-view and uncheck all options except the Start Menu then click 'OK'
You can also change other indexing options, like the file types to index, by clicking on the Advanced button.
