WSUSutil.exe will give you a library of command-line controls to manage a WSUS server implementation. You don’t need to install the WSUSutil.exe program separately because it is part of the WSUS software package. The program is resident in the Program FilesUpdate ServicesTools directory of the drive that holds the WSUS server. You need to be in that drive to issue WSUS utility commands. All WSUS commands start with wsusutil followed by a keyword and parameters. For example, wsusutil reset.
