What feature of Windows allows users to automatically update their software?

Windows Update is the feature in the Windows operating system that enables users to automatically download and install updates for the operating system and other Microsoft software. This includes critical updates, security patches, and feature improvements, ensuring that devices remain protected against vulnerabilities and that users have the latest features available.

Windows Update operates in the background, checking for updates on a regular schedule, which can be adjusted by the user. Users receive notifications about the available updates and can set the system to install them automatically, thus minimizing the risk of running outdated software that may have security flaws or bugs.

Other options such as Windows Security, Windows Defender, and Windows Explorer serve different purposes. Windows Security is a suite of tools and features related to system protection, while Windows Defender specifically refers to the antivirus component. Windows Explorer pertains to the file management system in Windows, allowing users to navigate and manage files and folders but does not handle software updates or system maintenance tasks.
