Skipping the WSUS server and using Microsoft Update services This will search and download all patches available for the target system on the Microsoft Update services server.
For example: WuInstall.exe /download /UseUpdateService MicrosoftUpdate You can change this behavior via the optional parameter /UseUpdateService with the options MicrosoftUpdate, WindowsUpdate, WSUS, or Default. If there's no WSUS server configured, it will use the standard Windows Update server.
Therefore, if the target system is configured to download updates from a Windows Server Update Services (WSUS) server, WuInstall will search and download from a WSUS server by default. WuInstall is written in C++ and uses native Windows Update application programming interfaces (APIs). Note : When using WuInstall interactively on a local computer, always run it from a command line with elevated permissions. The log is a simple text transcript of messages with timestamps shown from the command prompt. This will scan the computer for missing updates, download them to the Windows Update cache folder (C:\Windows\SoftwareDistribution\Download by default), copy them to D:\WuInstall, and create an additional log file.
For example: WuInstall.exe /download_to 'D:\WuInstall' /logfile 'D:\myLog.txt' To use WuInstall, you always need to specify a single basic option followed by optional advanced parameters.
