"refuses to install the Anniversary update"
There's no rush. I have a test PC (so it is an almost pristine installation with no apps) that successfully installed the Creators Update and promptly refused to shut down. Whether it be shutdown, restart, safe mode, whatever, any attempt to turn the system off just got stuck at the annoying circle of dots, requiring a hard power-off (and consequent disc corruption) to actually turn off.
So it's unusable and I've reverted to the previous disc image. I don't care, because it's a test PC and I *have* the previous disc image. But if I were a normal user, with valuable data on my PC and probably inadequate backups, the Win10 policy of forced updates would have borked the machine and there is frankly almost nothing that Joe User can do about this because a PC that isn't connected to the internet isn't useful to Joe User.
