If you are a typical computer user, then the fewer services your system runs the better. The following will assist you in determining which services you can turn off in Windows XP Pro/Home, to improve performance, boot time, and to effectively increase your security level.
Every running, but unused, service on your machine may well be an unnecessary security vulnerability. If a service is not required for authorized users and system functionality, turn it off.
The following recommendations have been compiled from personal observation over the course of the last few years. The suggested settings may not be appropriate for your machine.
Before you begin, it is important to remember that if a particular service is disabled, any other service/services that explicitly depend on it will fail to start. Read the Properties information carefully and make sure you understand what the service does/does not do.
Adjusting services settings incorrectly has the potential to leave your computer in an unbootable condition. It’s important that before you begin making changes to system services, you have fully functional backups of your system/data.
If you are prepared to go ahead then open the Control Panel, Administrative Tools, Services. Right click on a service and open Properties to make changes to the startup type (first check the tab Dependencies).
First of all Open "Run" and Then type "services.msc" and Hit Enter, Then Services Window Will appear Now Apply Those Following Methods on That
