Which of the following is used to manage startup processes in a Windows environment?

In a Windows environment, MSConfig (System Configuration) is specifically designed to manage startup processes. This tool provides a user-friendly interface to enable or disable software applications and services that run at startup, as well as allowing users to manipulate system settings that can impact the boot process.

MSConfig allows users to troubleshoot issues related to startup and can be used to improve system performance by avoiding unnecessary applications from launching during booting. Additionally, it offers options to select which operating system to boot, which can be useful in multi-boot configurations.

While Task Manager can also show currently running processes and applications, it does not offer direct management of startup processes in the same way that MSConfig does. Device Manager is focused on managing hardware devices and drivers, while Event Viewer is utilized for logging system events and troubleshooting rather than managing the startup sequence of applications.
