Software Update Services
) is a tool for centralizing the update
of Microsoft Windows
systems in a network
, developed by Microsoft
SUS works on a server
updates for the specified versions of Windows from the remote Windows Update
site, operated by Microsoft. The clients can then download updates from this internal server, rather than connecting directly to Windows Update. This simplifies the management of updates and saves bandwidth
SUS has been superseded by Windows Server Update Services, which use the same principles but allow updating of different Microsoft products, not only Windows.
Support for SUS by Microsoft was originally planned to end on December 6, 2006 , but based on user feedback, the date was extended to July 10, 2007
An alternative tool for distributing updates and software to Windows systems is the Microsoft Systems Management Server, designed for use in large networks.
