WSUS is a service you run inside your organisation - on one or more servers which you configure to serve software updates to one or more AU clients. You can configure a WSUS server to download updates either from Microsoft or from another WSUS server within your organisation. Once you approve an update for installation, WSUS downloads it from configured upstream partner, and can then issue these updates to clients that request it. You can approve any update for some, all, or none of your computers. Once an update is approved, the targeted WSUS clients download the update using the Windows AU client. WSUS also provides reports on which clients have, and have not, had which updates.
