Which of these is NOT a function of the Device Manager?

The correct choice highlights that deleting files from the computer is not a function of the Device Manager. Device Manager is a Windows tool that serves specific purposes related to hardware recognition and management. It allows users to view all devices installed on the system, update device drivers to ensure that hardware operates with the latest features and fixes, and remove devices that are no longer needed or are malfunctioning.

In contrast, deleting files refers to managing data stored on the computer, which is handled by file management systems and not by the Device Manager. File deletion falls under the capabilities of the operating system's file explorer or other utility programs designed for file management, rather than the device management functions that Device Manager is intended for.
