ColdFusion11 Update13

While it's indeed true that the updater should stop the CF services, just beware that sometimes it does not succeed, and in that case you may find that the update fails (whether it indicates that or not. You may find that either that the CF Admin may show that the update is still not applied, or you may find that CF did come down but can't come up, or the Admin doesn't work, or your code doesn't work).

I'll share that for any readers who have trouble applying updates, I have an extensive blog post that highlights the common problems and solutions with applying updates (in 10, 11, or 2016 and beyond).

Same about updating the JVM/JRE that CF uses (and as haxtbh said, no, most CF updates don't update JVM. You generally have to do it yourself.) While on the surface it's a 5-minute job for those who know what they're doing, it's easy for someone to make any of many little mistakes that could leave CF unable to start. I have a blog post also on those common problems updating the JVM CF uses. Hope that may be helpful to some readers of this thread.
