Windows 10 RS1 Insider Preview Pro 14388 x64 en-US Untouched ISO

Windows 10 Redstone 1 (1607) PRO Insider Preview Build 14388 en-us Untouched ISO

Untouched ISO made from the update ESD. English only.
Nothing added/nothing deleted.
This was created by using the install.esd file and using an ESD Decrypter to create the .iso choosing the "compressed install.esd" not the standard wim one, which is why the size is smaller than some others. It has no frills, nothing added nor nothing changed. Just check the box that says you do not have a key then you have 3 days to use whatever method you want to activate.
