Thanks for the quick reply. I am using your updates to slipstream via MDT and have just tested an installation minus the IE11 exe. I thought I saw a cab version of IE11 before but must have been mistaken so will use MDT to install IE11 amongst other non integratables post integrate unless I'm mistaken. If anyone has any experience doing this with MDT then I'd appreciate any suggestions or experience. All went well with the exception of Windows attempting to logon to the local Admin Account after every reboot. I'm not sure whether one of the updates has caused this or a corrupt file but I'll look into it. As of today the following additional KB files needed to installed post integrated Windows install. Security (Important) KB2706045 KB2861855 KB2862152 KB2909210 KB2912390 KB2965788 - (Failed to install first time, possibly one off) KB2791765 KB2904266 Non-Security (optional) KB2574819 KB2592687 KB2830477 KB971033 KB2923545 As always, appreciate your hard work.
