that I am unsure about, but updating windows like installing updates, and patches, if you download at least IE 4.0, then goto windowsupdate.microsoft.com, you can download all the updates for your version of IE and windows, also on your product, have you considered cleaning out some of the code so that it wont use so many activeX, I may recomend using some API whereever possible(40K as compared to 10 megs sometimes).
