Detailed explanation-1: -Microsoft Windows services, formerly known as NT services, enable you to create long-running executable applications that run in their own Windows sessions. These services can be automatically started when the computer boots, can be paused and restarted, and do not show any user interface.

Detailed explanation-2: -Take advantage of Windows services to build applications that you want to run in the background or execute automatically at predefined intervals of time. A Windows service is a long-running application that can be started automatically when your system is started.

Detailed explanation-3: -Most Windows Services start when your computer boots and run continuously, 24×7 in the background. For those services, the system boot time is a reasonable approximate.

Detailed explanation-4: -Windows Services cannot start additional applications because they are not running in the context of any particular user. Unlike regular Windows applications, services are now run in an isolated session and are prohibited from interacting with a user or the desktop.

Detailed explanation-5: -The Windows operating system makes use of these applications or services to do what an OS does, such as manage network connections, play sound, provide file system functionality, provide security and authentication, display colors and interact with the user through the GUI.

Detailed explanation-6: -You can set the Startup type of a Windows service to be: Automatic: the service starts at boot time. Automatic (Delayed Start): the Windows service starts only after the system has loaded all the other services set to start automatically. Manual: the Windows service starts only when it is needed.
