If you ever need to disable this annoying pop-up for Windows 2003 Server, here's how: - Click on Start --> Run... Type in services.msc and press the [Enter] key. The services window should show up now. Find an entry in the list for "Automatic Updates". Right-click on "Automatic Updates" and select "Stop". The dialog message box should not pop up now for the rest of the Windows session. I find this particular useful for automation, where this dialog box could pop-up and then cause the automation scripts to fail and stop running. In addition, you make be working with software products which requires you to have an older Windows service pack to be installed instead of the latest one so that the product can be installed correctly.
