Windows Services, also known as Windows NT services, are long-running background processes that run independently of any user session on a Windows operating system. They provide functionality and perform tasks that can run without user interaction or even when no user is logged into the system.
- Windows service is a computer program that runs in the BACKGROUND to execute some tasks.
- Windows services can be started AUTOMATICALLY or manually.
- You can also manually pause, stop and restart Windows services.
Here are some key characteristics and features of Windows Services:
Background Process: Windows Services are designed to run in the background and do not require a user interface. They typically start automatically when the operating system boots up and continue running until they are stopped or the system shuts down.
No User Interaction: Unlike applications that interact with users through a graphical user interface (GUI), services do not have a user interface. They typically operate silently in the background, performing tasks or providing functionality without requiring any user interaction.
Independent of User Sessions: Windows Services are not tied to a specific user session or login. They can run even when no user is logged into the system and can continue their operation regardless of user activity or session changes.
Controlled by the Service Control Manager (SCM): The Service Control Manager is a component of the Windows operating system responsible for managing Windows Services. It handles service startup, shutdown, and monitoring, allowing services to be started, stopped, or restarted as needed.
Wide Range of Uses: Windows Services can perform a variety of tasks and provide various functionalities. They can handle background processing, perform system maintenance tasks, act as servers for network communication, monitor resources or events, and more. Examples of Windows Services include the Print Spooler service, SQL Server service, and the IIS (Internet Information Services) service.
Configurable and Customizable: Services can be configured and customized using the Service Control Manager or by modifying service-specific settings. Administrators can set startup types (automatic, manual, or disabled), security settings, recovery options, and more.
Logging and Error Handling: Services often include logging mechanisms to record events, errors, and other relevant information. This allows administrators to monitor service activity, troubleshoot issues, and perform debugging if necessary.
Windows Services provide a way to run long-running processes in the background, performing critical tasks or providing functionality that doesn't require user interaction. They are an integral part of the Windows operating system and play a significant role in various system services and server applications.
