Patching the Windows Operating System in an organization with multiple desktops and many flavors of operating systems is a mammoth task. It is vital for any Systems Administrator to ensure all systems are properly patched and updated to safe guard against virus, worms, and Trojans. The biggest challenge in running Windows Update on individual machines is the inconvenience of visiting each desktop and approving the updates manually. Moreover, the amount of bandwidth used at each desktop to download the updates is huge not to forget the lack of centralized reporting.

So why do we need a centralized patch management policy? Well, the answer is simple – the systems are prone to risks and threats when exposed to the Internet or medias like USB pen drives, wireless networks and devices, etc. We all, at some point, might have experienced or read about the havoc caused by Blaster or the Sasser worms. Today software vendors have stepped up the releases of emergency and critical updates in a formalized manner to encounter these threats. Microsoft’s Patch Tuesday is a good example that highlights that. To learn more about this program, click here.

WSUS from Microsoft is a boon to Network and System Administrators in this scenario. WSUS (Windows Server Update Services) is basically designed to run on a company’s network and automate the process of patching. This free product from Microsoft does a fair job of streamlining the overall patch management process of an organization with centralized reporting. For a Network or System Administrator it is just a simple task of installing the WSUS server on a system and then configures all Desktops to use the WSUS server for software updates. This can be easily achieved by creating a group policy and linking the policy to the correct OU using Group Policy Editor. The Desktops would automatically announce their current status to the WSUS server with details like which patches are needed to be installed, which patches have failed to install, which patches have been successfully installed, etc.

In a nutshell, WSUS seems to be a good product especially when there is no price tag attached to it and starting with WSUS 3.0 the reports have also improved over its predecessor.
