Infoworld has an article on Microsoft's planned forced upgrade to Internet Explorer 7. The upgrade is to take place on Feb 12th as part of Windows Server Update Services. Apparently Microsoft has also posted guidelines for admins who would prefer to stay on IE 6.
IE 6 currently makes up about half the IE traffic going to the Citrix support site. It will be interesting to see how traffic to our various Citrix websites changes after Feb 12th.
