And unscheduled updates and reboots is the IT department failing to do their job. Last Windows shop I worked at, every single update and system restart was scheduled days if not weeks in advance and the systems mostly only went down unexpectedly when hardware was failing, which is pretty OS-agnostic.

Of course, if you just have a few fly-by-night Windows systems that aren't centrally managed, you're going to have issues.

Why do I keep seeing this at windows shops and not Linux shops? Maybe it is just selection bias, I have only had 16 contracts in the past 20 years not quite a statistical level sampling yet. But I would seriously like to explore non-selection bias reasons why this IT departments seem to fail like so often using windows and not as often or at least not as publicly otherwise.

I think it depends. In my experience, this tended to be more of a problem in places that had mixed systems, or allowed people to BYOD. Every place that was running windows exclusively tended to have a halfway reasonable AD setup and at least someone in IT who was intimately familiar with administrating a fleet of Windows machines.

On the failing CI, I suspect it was more a culture thing than a specific technical detail thing. Windows shops often try to purchase solutions to their own organization's failures, like the crowdstrike thing (Yeah I know some Linux machine were impacted but it was like a thousand to one).

There is a non-zero amount of technical failures, but not enough to explain the vast disparity I have witnessed and keep witnessing.
