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 following the steps below. It is recommended that you disable indexing for the other locations other than the Start Menu for maximum performance. Bear in mind that while this tweak speeds up your overall system performance, it will also slow you down when searching for files in those locations. Click on the Start Button and enter Indexing Options. Hit Enter and the Indexing Options should load. Click on the Modify button, followed by Show all locations. Scroll through the tree-view and uncheck all options except the Start Menu. Hit OK. Note: For advanced users, you can also change other indexing options, like the file types to index, by clicking on the Advanced button.
