His characterization of Current Branch for Business (the 'Defer Upgrades' toggle in the Update settings pane) as blocking security upgrades for a year is a bit off the mark. CBB defers major feature upgrades, like the Anniversary Edition which started rolling out recently, but you continue to receive updates for the build you're on -- including security updates. You'll eventually receive major upgrade build N when build N+1 has rolled out to consumers, and when N+2 rolls out, N becomes unsupported. This option is only available for Pro and above, so Home users are essentially stuck in permanent beta-testing mode.
