The SUS Server can automatically download all the updates that have been made available by Microsoft for the selected operating systems and language versions. At fixed intervals, you must go to the SUS administration page and see whether new updates are available, whose installation you have to approve. The best way of doing this is to register at http://www.microsoft.com/security/bulletins/alerts.mspx in order to automatically receive e-mails when Microsoft has made new updates available.
In order to ascertain which updates are available, open the SUS administration page. Through Approve Updates,
you can determine which updates have been downloaded in the computer. The new updates are tagged with New
in the list.
