You can close multiple tasks in Task Manager by selecting them and then clicking the "End Task" button.
Here's how:
- Open Task Manager: Press Ctrl+Shift+Esc or right-click the taskbar and select Task Manager.
- Select Multiple Tasks: Click the first task you want to close. Then, hold down the Ctrl key and click on each additional task you want to close.
- End Tasks: Click the End Task button in the bottom right corner of the Task Manager window.
You can also right-click on a selected task and choose End Task from the context menu.
Note: Closing tasks forcefully can sometimes lead to data loss. If you're unsure about closing a task, it's best to save any unsaved work before proceeding.
