Creating a rule for Windows Update on Windows XP


By default, Windows Update will only run in Internet Explorer when run on Windows XP. (Windows Update has its own Control Panel Applet on Windows 7). If the Block Other Requests setting for Internet Explorer is enabled in Catalyst, Windows Update will fail to run properly on Windows XP. To enable Windows Update to function, a specific Catalyst rule must be created to enable Windows Update in Internet Explorer in this scenario.
