Install Windows Desktop Update on NT systems — without jumping through IEAK hoops or uninstalling/reinstalling IE4SP2. The trick is a little known command line utlity that the IE5/IE6 installer accepts: IE6Setup.exe /C:”ie6wzd /e:IE4Shell_NTx86 /I:Y” (replace IE6 with IE5 if installing IE5). This also works on a PC with IE6 already installed.
