Which of the following is NOT a function of the Control Panel?

The answer is correct because performing real-time virus scanning is not a function typically handled by the Control Panel in an operating system. The Control Panel is primarily designed to manage system settings, user accounts, and applications, providing a centralized interface for adjusting how the operating system operates.

Managing user accounts is a key function of the Control Panel, allowing users to create, modify, and delete accounts, as well as manage passwords and privileges. Configuring system settings also falls under its capabilities, enabling users to adjust hardware settings, display options, and system preferences.

Uninstalling applications is another task that the Control Panel can facilitate through its program management features, allowing users to view installed applications and remove them if desired.

In contrast, real-time virus scanning is typically a function of dedicated antivirus software rather than a feature found within the Control Panel. Antivirus programs operate independently to monitor system activity for potential threats, perform scans, and provide real-time protection against malicious software. Thus, it is accurate to state that real-time virus scanning does not fall under the Control Panel's functionalities.
