In the Windows operating system, where do you navigate to install new operating system features?

In the Windows operating system, the Control Panel is the correct location for installing new operating system features. The Control Panel provides a centralized interface for configuring various system settings, managing hardware and software, and adding or removing features. Within the Control Panel, users can access options like "Programs and Features" to manage installed software, including enabling or disabling Windows features.

The other options provided do not serve this purpose. Task Manager is primarily used for monitoring system performance and managing running applications and processes. Device Manager focuses on overseeing and managing the hardware devices attached to the computer. File Explorer is used for navigating the file system and managing files and folders, rather than adjusting system settings or adding features. Therefore, the Control Panel is the best answer for installing new operating system features.
