Ancient industrial machines use ancient windows computers. This has been known forever. There's a whole niche industry of very expensive ram and hard drives and other components keeping this industry going

Yeah man. Details are going to be fuzzy here, but I think it was only in recent memory where Boeing upgraded the planes in Japan to no longer need floppy disks.
Yes i still use floppy disks regularly for my cnc plasma table
I run a computer on Win7 at work, because it needs some important legacy software. It can't be containered because it has a nasty licence manager.
And my oscilloscope runs on Win98.
I know it's not exactly the point of the article but for a lot of things, I reckon a good amount of 'innovation' was pretty pointless. I personally don't think I ever needed anything that Office 2003 can't do... (Of course I don't use any MS office to begin with but you get the point)

Nuclear silos.. is that early dos system I believe?
As long as things are not connected and not trying to add newer stuff , what's the problem?
The elevator was running Windows XP.
Clearly an extreme case of overengineering. A elevator has no business running more than a few microcontrollers.
But how else can it be safe to connect to the internet?
You need to be on-site to fix it anyway, just access the debug port.
But how else can it book requests for priority access, and verify the credit card for whoever booked the elevator?
Ah, the blossoms of unimpeded, wild capitalism.
In highrises with lots of stops and users, it uses some more advanced software to schedule the optimal stops, or distribute the load between multiple lifts. A similar concept exists for HDD controllers, where the read write arm must move to different positions to load data stored on different plates and sectors, and Repositioning the head is a slow and expensive process that cuts down the data transfer rate.
This requires little more than a 286. It's an elevator. Responding in times measured in seconds. What kind of computations do you think are required here? Imaginary quaternion matrixes? Squared?
Yes, but if you have it as a Windows program it's easier to configure on a screen with mouse and keyboard, change settings, display help files or give the source code to someone else to make changes or add features.
also it was probably not too expensive to grad a bog standard PC off the shelf and do it on that. I've see raspis in the wild doing tasks like that. and those will be outdated by the time they're replaced too
It's probably only the screen component that is running an old version of embedded windows.

I would still be using Windows 7 if it was safe to connect to the internet.
I can't believe government systems are just open to cyber security like that.
Are there not cyber terrorists for some teenager that has tried to do anything with these unsecured systems?

I'd still be using Windows 7 if I could.
MS DOS 6.6 for me - I enjoy the power of a 286 processor and much smaller instruction sets.
:O

Mail sorter for a company I worked for uses Windows 3.1.
My parents ancient HP from 1997, I sold the motherboard with popped capacitors for $250. I informed the buyer of the condition and he said he didn't care, he'd fix it, but they needed it for some legacy hardware their company functioned on.

I was tearing out ancient infrastructure for a new office and my eye kept going to a rectangular square box on the wall. Finally realized it was a PC! The cause of death was clear, PSU fan died, killed itself from heat. It was a form factor I had never seen, but standard nonetheless. It was running an answering machine system in DOS, still worked! Such a rare machine I've only found a single reference on the web and a single video about it. 1999, 486XS (I know, would kill for a DX, it's soldered on), upgraded from 2x 2MB SIMMs to a whopping 2x 64MB SIMMs. Imagine what that would have cost in the day!
LONG story, but I got it running Windows 95b. 3.1 was just too much challenge to get it networked and happy. Much pain was removed when I got a USB floppy emulator. Can't do jack without a floppy! Broke the network card drivers, need to start over. Had it running Doom with a legit SoundBlaster card and could RDP into over the network.
It was an amazing journey getting it all together and updated. Most of that knowledge is gone from the internet, and I sure don't remember all the tricks. Going to be my first token ring machine! LOL, had to get parts from Romania and trash cans.
