mainly I agree to you, but …
I want to clearly point out that “Gandalf´s”, “DLCboot” (“new”)HirensbotCD (as well as other floating around “ready to use” Window-PE based CD/DVD-images are completely illegal!
That is the reason that I only mentioned “Aomei Pe Builder” : that is (to me the only) known legal + comfortable solution to build a standard or even extended Windows PE. Of course You can use all other legal PE-Builders (which are the basis for Aomei´s Windows PE), but that needs more time. knowledge, thoughts and trials to get into it…
