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, however if you do not have more files in the computer, it is fine if you disabled the service.
The indexing service seems to eat up a lot of CPU on every machine, especially when you have more files, it could definitely make the system slow.
Follow the steps below to accomplish the task:
• 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.
