Windows 7 / Getting Started

Windows Server Update Services

Windows Server Update Services (WSUS) is a version of the Microsoft Update service that you can host on your private network. WSUS connects to the Windows Update site, downloads information about available updates, and adds them to a list of updates that require administrative approval. To deploy updates to Windows 7 clients, you must use WSUS 3.0 with SP2 or later versions.

After an administrator approves and prioritizes these updates, WSUS automatically makes them available to any computer running Windows Update (or the Automatic Updates client on earlier versions of Windows). Windows Update (when properly configured) then checks the WSUS server and automatically downloads and installs updates as configured by the administrators. As shown in Figure below, WSUS can be distributed across multiple servers and locations to scale to enterprise needs. WSUS meets the needs of medium-sized organizations and many enterprises.

WSUS can scale for enterprises

WSUS requires at least one infrastructure server: a computer running Windows Server 2003 SP2 or later server operating systems with the Microsoft .NET Framework 2.0 SP1 or later versions. Additionally, the server must have Microsoft Internet Information Services (IIS) 6.0 or later versions installed.

Important To deploy updates to Windows 7 computers, you must have WSUS 3.0 with SP2 or later versions.

The WSUS interface enables administrators to perform the following administrative tasks:

  • Synchronize the WSUS server by downloading a list of updates from Microsoft.
  • Approve updates for distribution to client computers.
  • View a list of computers that successfully installed updates or experienced problems installing updates and determine exactly which updates have been installed.
