To customize startup programs in Windows, which tool should you use?

Using the System Configuration tool is the most appropriate way to customize startup programs in Windows. This utility allows you to manage which programs are loaded when the operating system starts, giving you control over the startup process. By using the System Configuration tool (commonly referred to as "msconfig"), you can enable or disable specific startup programs, reducing the boot time and improving overall system performance.

The system provides a straightforward interface for users to check or uncheck items in the Startup tab. This capability is particularly useful for troubleshooting purposes, as it allows users to identify applications that may be causing issues during startup.

While other tools mentioned do serve important functions, they are not specifically tailored for managing startup programs. Task Manager does have a startup tab that can show you a list of programs set to run at startup, and it allows basic enabling or disabling; however, it lacks the comprehensive options found in System Configuration. Control Panel provides a general area for managing hardware and software settings but does not specifically address startup configurations. Device Manager is focused on managing hardware devices and their drivers, making it irrelevant for users looking to customize startup applications.
