Each update can be installed by running it. You may want to script it to install all updates in one go using the /quiet /norestart switches. (To integrate the updates into the installation media, extract the msp files and place them in the Updates folder. Any patches placed in this folder will be applied during initial install only.) Full list of supported switches for the patches is as follows: /extract:[path] Extracts the content of the package to the path folder. If a path is not specified, a Browse dialog box appears. /log:[path of log file] Enables verbose logging for the update installation. You must also include the file name in addition to the path information. The command does not create a folder. Therefore, you must use an existing folder name. In addition to the specified file name, a separate log file is created for each .MSI file that you run. /lang:lcid Sets the user interface to the specified locale when multiple locales are available in the package. /quiet Runs the package in silent mode. /passive Runs the update without requiring user interaction. /norestart Prevents prompts to the user when a restart of the computer is needed. /forcerestart Forces a restart of the computer when the update is complete. /? /h /help Displays a help message. Thanks for the additional information on this and sorry for taking so long to reply. I just found out that even though a tool I was using told me I had the 64bit version installed, it turns out that it is the 32bit version, so I have had to dump all the updates and start again by getting the x86 files! One question further if I may..... Am I correct in thinking that you cannot get Microsoft Office 10 Pro Plus to automatically update itself using the Windows Update Tool? Thanks.
