I remember a while ago that I could download any Windows/Microsoft update I wanted by going to a site on Microsoft.com, and just clicking download against any update.
It also had a brilliant search feature so that I could type either an update number or a basic search term and it would find all the certified packages that can be delivered through Windows update (WHQL drivers etc.)
It is driving me mad, I have spent the best part of the day (along with other tasks!) trying to find this link!
Does anyone know what it is?
