I am seeing quite a few "Optional" updates for Windows 10. Some of those are related to the Update process. I realize they may just be realigning the Update servers or some necessary change in order to keep the update process working, but are they doing more? Making changes to the Update process might mean we will loose control of whether certain updates are installed or not, like Window 10. If that were to be the case, Microsoft could make changes to the OS, a piece at a time in such a way that by 2016, Windows 8.1 would technically be Windows 10. I am not referring to just "aligning" 8.1 to 10 for upgrade purposes. If that is all they are doing, it might be fine, but could Microsoft actually have a more ambitious plan in mind. Maybe using such things as what is shown in the comments about KB3065988. What might qualify as a "Corporate" device..?
