A "Sessão de logon" (logon session) is a period during which a user is authenticated on a system and has access to resources. In the Windows environment, managing user logon sessions is crucial for security, auditing, and troubleshooting. This article will guide you through the process of managing logon sessions using various Windows tools and commands.

Understanding and managing logon sessions can help administrators monitor user activity, enhance security by identifying unauthorized access, and troubleshoot issues related to user authentication. In Windows, tools like Command Prompt (CMD), PowerShell, and built-in utilities can be used to manage these sessions effectively.

Examples:

1. Viewing Active User Sessions Using CMD:

   You can use the query user command to view active user sessions on a Windows machine.

   query user

   This command will display information about all users currently logged on to the system, including their session names, IDs, and states.

2. Logging Off a User Session Using CMD:

   To log off a specific user session, you can use the logoff command followed by the session ID.

   logoff <session_id>

   Replace <session_id> with the actual session ID obtained from the query user command.

3. Viewing Active User Sessions Using PowerShell:

   PowerShell provides a more flexible way to manage user sessions. You can use the Get-Process cmdlet to view user sessions.

   Get-Process -IncludeUserName | Where-Object { $_.UserName -ne $null }

   This command will list all processes along with the usernames associated with them.

4. Disconnecting a User Session Using PowerShell:

   To disconnect a user session, you can use the Stop-Process cmdlet.

   Stop-Process -Id <process_id> -Force

   Replace <process_id> with the actual process ID of the user's session you want to disconnect.

5. Using Task Manager to Manage User Sessions:

   Task Manager is a graphical tool that can be used to manage user sessions. To access it:

   • Press Ctrl + Shift + Esc to open Task Manager.
   • Go to the Users tab to view all active user sessions.
   • Right-click on a user session to either disconnect or log off the user.
