But boiling this down even more, what it translates to is users can accept the latest security updates without being forced to download anything else. You get a lean mean operating system and wave goodbye to security updates being dependent on you accepting every feature, bug patch or new telemetry tracker Microsoft throws at you.
How Microsoft has done this is by making its Windows 7 and Windows 8 Monthly Rollup patches (a collection of anything you may have missed) easily dividable into security patches and everything else.
