if I want to reinstall a Windows 8.1 on a notebook, what is the very latest build available? 1- Is it Update 3 build 9600 still ?? 2- Is there a newest ESD ?? 3- Is there a upgraded 8.1 ISO containing all hotfixes integrated? 4- Is there an UpdatePack?? For option 4 I just see that user 3zero3 made an UpdatePack... someone tested it? can it works with every Language?
