What is the purpose of Windows Update?

Correct answer: Automatically download and install security patches and feature updates

Option B is correct because Windows Update is the built-in Windows service designed to automatically download and install security patches, cumulative updates, and new feature releases from Microsoft, keeping the operating system protected and current. Option A is wrong because user account management is handled through the Computer Management console, Local Users and Groups, or Active Directory, not Windows Update. Option C is incorrect because system performance monitoring is the role of Task Manager, Performance Monitor, or Resource Monitor. Option D is wrong because uninstalling programs is done through Programs and Features or the Settings Apps panel, not Windows Update.
