Operating system platforms never exist statically. Once installed, with the emergence of new content, the operating system needs to be patched and updated. This ensures performance, reliability and security. But enterprise deployment presents challenges.

When IT administrators have to update dozens, hundreds, or even thousands of physical and virtual machines, there can be potential negligence and errors even in data centers. Administrators need to find a tool that can help manage OS updates over the corporate network. The Windows Server Update Service (WSUS) is one such native tool.

WSUS is a server-based tool available for Windows Server 2012 and Windows Server 2012 R2 management and supports Microsoft enterprise product updates. This tool simplifies the update process and helps ensure that all servers and systems are updated correctly and in a timely manner. This also avoids the time-consuming and error-prone phenomenon of inventory in each machine. WSUS was introduced in 2005 and is currently version 4 released at the end of 2012.

In most cases, a single server can be configured as a WSUS server. The WSUS server connects to the Microsoft Update and caches available updates and patches. Administrators can use the WSUS server to check the installation, accept update status reports from some machines, and push cached updates to specific systems. This allows IT administrators to centrally manage and automate software updates. In addition, some non-critical systems or machines located in non-critical network areas can be directly connected to the Microsoft Update.

For the WSUS server role on Windows server 2012 R2 and NET Framework 4.5, hardware requirements are usually simple, but data center developers should strive to meet or exceed these requirements. Requirements include at least one 1.4GHz or faster CPU, additional memory for 1.5GB (excluding requirements for the Windows operating system), 10 GB of storage, and at least a 10/100MB Ethernet connection. Most servers can meet these needs. The WSUS server can be configured with a virtual machine.

Twelve new cmdlet have been introduced in Windows Server 2012 and 2012 R2, and PowerShell makes it easy to write WSUS functions (or add to existing scripts). By creating scripts, administrators can automate activities and help maintain consistency across data center activities. For example, Add-WsusComputer can add specific client systems to the target group, Get-WsusUpdate can get details of available updates, and Approve-WsusUpdate can apply an update to the system. Other cmdlet can provide additional control over the acquisition and use of WSUS services.
