If you have an iso with Update 1 you don't need to install the Updates in the April 2014 folder. If you have the latest Windows 8.1 ISO with Update 3 integrated you don't need to install the updates in the November 2014 folder. Simple as that. I also have a folder with a bunch of hotfixes that Microsoft never released on Windows Update, that fix a number of issues.
I'll see where I can upload it, and I'll post a link here.
