Default settings for servicesIf you have a typical installation, many services are configured as "automatic" (that is, they start automatically when the system starts or when the service is called for the first time). If a service is configured as "manual," you must start the service manually before it can be loaded by the operating system and made available for use. If a service is configured as "disabled," it cannot be started automatically or manually. For more information about configuring service startup, see To configure how a service is started. For more information about starting a service from the command line, see Net start.
The following table lists the default services for a typical installation of Windows XP Professional, along with their default startup settings. Your list of services might be different, depending on the components selected during installation and any additional programs that have been installed.
