I am trying the IE 10 removal and manual install of IE 11. I'm not sure how to tell if all the previous updates are uninstalled without cross-referencing all the KB numbers. I will report back to this thread with results.
Also to note, before uninstalling IE 10, I often went 5 - 7 days without NSI memory consumption spinning out of control. Sometimes it happens within 24 hours. Sometime longer. It is very difficult to nail down what the cause is.
