There are many services in Windows 2000 / XP we often use, what is these services do? What do we need? Don't you need it? Here I am a presentation to everyone.
Win32 Services consists of 3 parts: Service Applications, Service Control Programs, and Service Control Manager. Where the service control manager maintains the service data in the registry, the service control program is a module that controls the service application, which is a bridge between the control service application with the service manager. The service application is the host program of the service, and he is an executable code for one or more services. We can find it in the Control Panel - Management Tool - Services. You can modify their current status and start-up mode. It has three ways: "Auto" is when the computer is started or when it is required. "Manual" is that the "Net Start" command can be turned off through the "NET Stop" command in the command prompt, "disabled" means that before changing the start-up method, not starting.
In many serves, many of them are interdependent, so we can't stop a service, otherwise it is likely to cause the system's abnormal situation, but some services have no effect on us, but also occupy With our valuable system resources, there are many programs that we cannot use, which can be closed, thus achieving the purpose of saving resources.
