Where can you find out what applications are running in the background of Windows 10?

The correct answer focuses on the Notification Area, also known as the system tray, which is located on the right side of the taskbar in Windows 10. This area displays icons for various applications that are running in the background, as well as system notifications and quick access to certain tasks, such as network settings, volume controls, and power options. By clicking on the icons in the Notification Area, users can often see the status of applications and sometimes access their settings or features directly.

In contrast, while the Taskbar provides a visual representation of open applications, it primarily shows the ones that have windows currently displayed to the user. The Start menu serves as the main hub for launching applications and accessing system settings but does not display background applications directly. Quick launch is not a prominent feature in Windows 10, as it was part of earlier versions and has been replaced with pinning applications to the taskbar. Therefore, focusing on the Notification Area provides the most accurate information about which applications are actively running in the background.
