Write an event to the event log to allow a service to interact with users. The service does not require a logged-in user in order to execute and run under the context of any user including the system.

A service does not have a user interface or any visual output. Therefore, it can be easily run in the background to monitor an operating system without any user logging.

The Installutil tool is used to install a Windows application. The .NET class library provides some predefined installer classes that helps in application installation.

ClickOnce technology eliminates the difficulties in updating Windows-based applications, dependence of multiple application programs on shared components, and allowing permissions only to administrative users for application installations.

If a class derives from the ServiceBase class, the OnCustomCommand method is executed when the Service Control Manager (SCM) passes a custom command to the service.

When the CanHandlePowerEvent property is set to true, the power event command is passed to the service and then the OnPowerEvent method is called.

The ThreadPriority enumeration contains five priority members, which are a follows:

1. Lowest
2. BelowNormal
3. Normal
4. Highest
5. AboveNormal

The Join method is used to block the calling thread until a thread terminates.

The WaitSleepJoin state is used to specify that a thread is blocked.

Implement multiple threads using WaitCallBack delegate in an application.

Handle the DivideByZeroException using the try/catch block.

The Thread class of the System.Threading namespace is used to create a thread and execute it.

The Thread.IsBackground property is used to run a process in background. A thread is either a background thread or a foreground thread.
