What I really don't understand is why commercial stations (like burger king's, ice cream stands etc...) uses windows when all those computers do is show either videos or static images
Add to that, (at least here in Germany) BK is a franchise that sells licenses to franchise operators, so I doubt they have strict requirements on the actual IT setup, just the pictures they need to display.
So you have very normal, run-off-the-mill managers and IT services, the former unable to grasp that Windows 10 with constant updates and fuck-ups will constantly require the services of the IT guys, and the latter naturally profiting of that. The increased margin of not using Windows wouldn't be enough to compensate that, and an increased price for a Linux package is something very difficult to convince those managers of.
And then also IT-people well versed in Linux usually have clients who pay substantially more than simply outfitting non-IT businesses with IT-equipment.
I'm pretty sure I've never seen anything like that on LKML.
* Windows has been approved by management to be the only OS allowed on the computer network * The software for showing the static images / videos and whatever manages it will have been written on Windows or even DOS * The manufacturer of said machines whoever wrote their software was Windows Developer and it is cheaper just to ship a copy of Windows Embedded then to rewrite the software , QA and integrate it.
I have a piece of software that I get small support contracts for. I tell clients it is Windows only. There is nothing stopping me from deploying to Linux or even one of the BSDs (I think). I just can't be bothered to deal with differences in distros, going through a QA process etc when it won't really get me many more sales.
The companies that make that stuff started out with Windows, they have built a workflow to manage these devices on top of Windows, why switch now? It's not cost effective.
