They're probably deployed to a virtualized system to easy with maintenance and upkeep.
Updates are partially necessary to ensure you don't end up completely unsupported in the future.
It's been a long time, but I worked IT for an auto supplier. Literally nothing was worse than some old computer crapping out with an old version of Windows and a proprietary driver. Mind you, these weren't mission critical systems, but they did disrupt people's workflows while we were fixing the systems. Think, things like digital measurements or barcode scanners. Everything can be easily done by hand but it's a massive pain.
Most of these systems end up migrated to a local data center than deployed via a thin client. Far easier to maintain and fix than some box that's been sitting in the corner of a shop collecting dust for 15 years.
Real problem is not that it's just a damn lift and shouldn't need full Windows. It's that something as theoretically solved and done problem as an operating system is not practically so.
An Internet of Lift can be done with <32MB of RAM and <500MHz single core CPU. Instead they(for whoever they) put a GLaDOS-class supercomputer for it. That's the absurdity.
You’d be surprised at how entrenched Windows is in the machine automation industry. There are entire control systems algo implemented and run in realtime Windows, vendors like Beckhoff and ACS only have Windows build for their control software which developers extend and build on top with Visual Studio.
Siemens is also very much in on this. Up to about the 90s most of these vendors were running stuff on proprietary software stacks running on proprietary hardware networked using proprietary networks and protocols (an example for a fully proprietary stack like this would be Teleperm). Then in the 90s everyone left their proprietary systems behind and moved to Windows NT. All of these applications are truly "Windows-native" in the sense that their architecture is directly built on all the Windows components. Pretty much impossible to port, I'd wager.
So for maintenance and fault indications. Probably saves some time from someone digging up manuals for checking error codes from where ever they maybe placed or not. Also could display things like height and weight.
According to reports the ATMs of some banks also showed the BSOD which surprised me; i wouldn't have thought such "embedded" devices needed any type of "third-party online updates".
Its easier and cheaper (and a lil safer) to run wires to the up\down control lever and have those actuate a valve somewhere, than it is to run hydraulic hoses to a lever like in lifts of old, for example.
That said it could also be run by whatever the equivalent of "PLC on an 8bit Microcontroller" is, and not some full embedded Windows system with live online virus protection so yeah, what the hell.
I'm having a hard time picturing a multi-story diesel repair shop. Maybe a few floors in a dense area but not so high that a lack of elevators would be show stopping. So I interpret "lift" as the machinery used to raise equipment off the ground for maintenance.
The most basic example is duty cycle monitoring and trouble shooting. You can also do things like digital lock-outs on lifts that need maintenance.
While the lift might not need a dedicated computer, they might be used in an integrated environment. You kick off the alignment or a calibration procedure from the same place that you operate the lift.
how many lifts, and how many floors, with how many people are you imagining? Yes, there's a dumb simple case where there's no need for a computer with an OS, but after the umpteenth car with umpteen floors, when would you put in a computer?
and then there's authentication. how do you want key cards which say who's allowed to use the lift to work without some sort of database which implies some sort of computer with an operating system?
It's a diesel repair shop, not an office building. I'm interpreting "lift" as a device for lifting a vehicle off the ground, not an elevator for getting people to the 12th floor.
