If you want to get rid of the prompt and the upgrade, remove update KB3035583. You'll also want to hide it by right clicking the update and selecting "Hide Update" from within the available updates dialog area. This will stop Windows Update from installing it over and over and over again. Which it will do if you don't hide it. Also, it looks like for those like myself that have done this, it now appears to be a stand alone update with no KB identifier. You can do the same thing to this update; just Hide it! This work around will probably be overridden by some future update, but it will give you temporary respite from this windows 10 upgropalypse.
