It supports the entire Windows OS, such as DNS client, printer, Windows update service, plan task, Windows time service, alarm and other services. They are related whether the machine could run correctly. If you cannot manage these services properly, then it would influence the machine’s normal operation.
First of all, a service is a Win32 executive application or a process of .dll form executed by rundll32.exe. Different from common application, such as to open WORD, there’s a window coming out. But there’s no user interface for service. And you could not run relevant .exe application directly just by double clicking. So how Windows control a service? Windows service is managed by superior system service: services.exe, which takes charge of start, stop, run and pause of services. The most common operation we use is to finish relevant operation with Windows service MMC interface.
