If you don't use IE, this trick is for you...
Go into the security settings for IE, set all to the highest level for intranet & internet zones. Then add microsoft.com and windowsupdate.com as allowed sites. The IE engine is used for Windows Update Outlook Express (maybe even rendering Outlook, too?) for emails, so pictures won't display from external sources, another layer of security, but still allowing Microsoft sites to work properly.
