If there is one bloated and unnecessary service that you should immediately disable, it's definitely the Indexing Service built into Windows XP. The idea behind it is that you can search for files more quickly if it is enabled…. but you are using Google Desktop for that, right?
The indexing service seems to eat up a lot of CPU on every machine I've used, especially when you have the amount of files that I've got. Let's disable it.
- Navigate to the Services console via Administrative Tools.
- Double-click on the Indexing Service and change the startup type to disabled.
- Hit the stop button if it is started, which is likely, and then hit OK.
Yet another unnecessary service stopped!
