Performing system operations is a crucial part of managing a Windows system. Here are some essential commands for handling system operations.

tasklist: Display currently active processes

• Basic usage:

  C:\> tasklist

taskmgr: Real-time Process Monitoring

• Basic usage:

  C:\> taskmgr

This will open the Task Manager GUI where you can monitor and manage processes.

taskkill: Terminate Processes

• Basic usage (using process ID):

  C:\> taskkill /PID [process_id]

• Terminate a process by its name:

  C:\> taskkill /IM [process_name]

For example, to kill a process named "notepad.exe":

```bash
C:\> taskkill /IM notepad.exe
```

shutdown: Shutdown or restart the system

• Shutdown immediately:

  C:\> shutdown /s /t 0

• Reboot immediately:

  C:\> shutdown /r /t 0

• Shutdown with a message:

  C:\> shutdown /s /t 600 /c "System will shutdown in 10 minutes"

This will shut down the system in 10 minutes and display the provided message.

Understanding these system operation commands is essential for effectively managing and maintaining a Windows system.
