Windows Server Update Services 3.0 Class Library
Microsoft gives administrators full control over the update management process, eliminating the need for client computers to retrieve updates directly from Microsoft Update. WSUS administrators can specify the types of updates to download, create target groups of computers to receive updates, and determine which computers require updates before deployment. Administrators can approve updates for deployment automatically, uninstall updates, and generate reports to monitor update activity.
System administrators can use the WSUS API to determine which updates apply to a computer or group of computers, download those updates, and install them with little or no user intervention.
Independent software vendors and end-user developers can integrate WSUS features into computer management or update management software to provide a seamless operating environment.
The WSUS API is accessible by any language that supports Microsoft .NET, including Microsoft Visual Basic .NET, C#, and managed C++.
This documentation assumes that the developer is familiar with WSUS concepts and features and does not provide in-depth conceptual material. For conceptual material, see the WSUS Product Overview.
For information on the WSUS client API, see the Windows Update Agent SDK.
