I have a copy of ( Windows 7 Ultimate SP1 x64 ) by Murphy78. This is an absolutely Brilliant Copy. Anyway I get annoyed by the time taken up to install Updates after a Clean install of windows, Particularly .net updates. This vers of windows requires very little in the way of updates, Good Work. However there is one ( .net 4.5.1 ) and it takes ages to install. So I have been looking for a way of Slipstreaming it , and it becomes very complex particularly because m/s has not released an MSU copy of it. However I have noticed after Decompressing the ISO, that there is a folder there Named Net451. It contains two files ( Automated-Install-Script.cmd ) and ( NDP451-KB2858728-x86-x64-AllOS-ENU.exe ). I can't see any mention in the notes of how to use/apply them. If they were put there with the purpose of being applied during the install, that doesn't eventuate. Or are they there just for conveniance and ment to be applied after the install.??. Any help on this would be appreciated.
