What is the primary function of Windows Server Update Services (WSUS)?

Windows Server Update Services (WSUS) serves a crucial role in managing updates and patches for Windows operating systems and other Microsoft products within a networked environment. Its primary function is to deploy software updates to clients, ensuring that all systems are up-to-date with the latest security patches, feature updates, and service packs. This helps enhance system security and performance while reducing the risk of vulnerabilities that could be exploited by malware or attackers.

By acting as a central repository for updates, WSUS allows administrators to control which updates are distributed, monitor the installation status on client machines, and schedule update installations to minimize disruption. This centralized approach streamlines the update process and ensures consistency across all devices managed within the server's scope. The other options pertain to functions that WSUS does not address, such as resource management, security firewalls, or CPU optimization, making the ability to deploy software updates its defining feature.
