1. Start the task manager
Right-click the task bar and click ‘Start Task Manager’ (also see This video for more ways of starting the task manager)
2. Go the the ‘Processes tab’ and click ‘Show Processes from all users’
This step is necessary to prevent an ‘Access Denied’ error message when trying to logoff a user, and the main reason people look up this very information.
3. Click the ‘Users’ tab
4. Select the user you want to log off.
5. Press the ‘Logoff’ button on the bottom of the task manager window
Or, right-click the user, and then click ‘Log Off’.
6. A pop-up window will appear. Click “Log off user”, to log the user off.
Like the message says, the user will lose its unsaved data, so be sure it’s OK to log the user off.
