| User Context | Run under particular user accounts, which can be regional system, network service, or user-defined. |
Architecture of Windows Services
At the core of Windows Services is the Service Control Manager (SCM), which manages the lifecycle of services.
Significant Components
- Service Executable: This is the primary application which contains the service code.
- Service Control Manager (SCM): It handles service control demands and sends notifications of state shifts to services.
- Service Process: A dedicated procedure that hosts the service.
Lifecycle of a Windows Service
Windows Services have actually a specified lifecycle which includes:
- Start: The service begins its operations.
- Stop: The service stops running.
- Time out and Continue: The service can be briefly stopped and resumed without ending it.
- Shutdown: The service with dignity closes down when the system closes down.
Benefits of Windows Services
Windows Services offer various advantages that make them a suitable option for particular applications:
| Advantage | Description |
|---|---|
| Dependability | Automatically reboot if crashes take place. |
| Self-reliance | Operate independently of user sessions. |
| Scalability | Can work on numerous devices and be distributed. |
| Security | Can run under different user contexts for security. |
