How does Windows Server Update Services (WSUS) work?
WSUS centralizes update and patch management services onto one server. It stores the patch files in its own database, so the patches only have to be downloaded from the Internet once. Instead of each employee downloading software from Windows Update or Microsoft Update manually on each individual’s computer, updates are stored on WSUS and then automatically pushed out to each computer. Most important, WSUS deploys patches and software updates to computers and servers on your network. A daily report is created, showing you a “green check” when all updates are successful or detailing which ones may have other installation requirements.
