Vista has a much-improved search function, but it’s dependent on indexing the files and programs on your hard disk so they can be found quickly. When the indexing process is running, however, it can slightly slow down other programs you’re try ing to run at the same time.

You can select the locations you want to index; fewer locations will result in less indexing and thus better overall performance. On the other hand, you’ll get better search performance by indexing all locations. You can’t turn the indexing feature off completely, but you can adjust locations indexed by selecting Adjust Indexing Options in the left pane of the Performance Information And Tools applet.
