If there is one bloated and unnecessary service that you should immediately disable, it's definitely the Indexing Service built into Windows XP.
This service is used to index files for windows search. But the question is that why to use this slow and bulky windows desktop search when we have the Google Desktop...
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 run and type "Services.msc". Hit Enter.
- 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!
