Keeping Windows patched is not optional, but there are two ways to do it in Intune and small firms often pick the wrong one for their size. One is update rings you build and run yourself. The other is Windows Autopatch, where Microsoft runs the rings for you. Here is the honest difference and which one actually suits a small company.
What update rings are
You define the schedule. A pilot group that gets updates first, then a broad group a few days later, with deferral periods and deadlines you set. It is flexible and free with Intune, and it means you own the timing. The catch is you also own the watching. Someone has to check the rings are healthy, chase the devices that fall behind, and react when an update causes trouble.
What Autopatch does
Autopatch takes that running off your hands. Microsoft moves devices through rings, watches the rollout, and halts or rolls back when something goes wrong across the fleet. You set it up once and it keeps Windows, Office, Edge and Teams current without you building the schedule. It needs Windows Enterprise E3 or Business Premium, which most firms serious about security already have.
The honest trade
Rings give you control and cost nothing extra, but they are only as good as the person minding them, and in a small firm that person is busy. Autopatch gives up some fine control in exchange for not having to think about it, which for a ten to hundred person firm with no dedicated patch owner is usually the better deal. Control you do not have time to use is not really control.
What we pick
For most small firms we run Autopatch, because the whole point is that patching happens reliably without a person remembering to look. Where a client has a real reason to hold specific timing, a line of business app that breaks on certain updates, we use rings and mind them under Managed Intune. Either way the goal is the same, every machine current, and proof of it.
