Sometimes an application can reduce your computer's performance. You can use the Task Manager to end the application's performance.
Be careful when ending processes. If you end a process associated with an open program, such as a word-processing program, that program will also close and you will lose any unsaved data. If you end a process associated with a system service, some part of the system might not function properly.
- Right-click the taskbar and select Start Task Manager.
- Click the Processes tab.
- Select a process and click End Process.
