I'm reading this forum and many of it is for expert, by experts, maybe a beginner friendly thread for casual users might worth it, not only for me - I haven't decided if I want Home or Professional yet, as all forum members, I'm eligible for both, (thanks to Daz). - I would like either > the plain vanilla US version (of Home or Pro), used by most people, only US English is required (it should only display properly all these weird Asian characters in the browser, nothing more), but as a side question I ask: can I later add other OS languages? Not required now, but you never know. > OR the plain vanilla EU version (as far as I know, it is stripped from Skype, Media Center or something like that, the question is, does it save any disk space or battery life on mobile devices, or the only benefit if any is less clutter?), US English again, EU version US English, plain vanilla used by most people, if it exists in this combo, which is the product code for that, Home or Professional? - I have one clean machine, for the moment, I would like to produce more than one, a few, separate Digital Entitlements, that is, a few 'legal copies of Windows 10,' verify if the the Digital Entitlement is OK, then put them into the drawer for later. Can it be done with one physical hardware, with separate, clean installs? Now you don't need to call Microsoft anymore if you plan on moving one copy of Windows 10 to a new hardware. I don't plan to use Windows 10 on the Digital Entitlement hardware under any circumstance, this hardware is only creating the Digital Entitlement, or Entitlements, if more than one is possible. What are the fastest, easiest main steps, relevant posts here or elsewhere which not necessarily dive so deep into Windows 10 as you usually do, just help me achieving my aim?
