irvinMost of us don't want or need to know how the car engine operates. Most of us don't want to drive stick-shift. We want a car that only needs steering and braking, accelerating. That's why fully automatic cars are overwhelmingly more popular than stick-shift, regardless of which one is technically better. .
While here on the eastern side of the Atlantic manual transmission is overwhelmingly more common. In the UK and most of Europe if you pass your driving test in an automatic you aren't even legally allowed to drive a manual until you pass another test in a manual so pretty much everyone learns to drive in a manual. Only around 1/5 cars sold in the UK are automatics and that's the highest market share they've ever had.
In the UK we've lots of narrow, winding roads, hills and urban areas with narrow streets. Like the rest of Europe we've historically tended to go for smaller engines in a relatively high state of tune while the US historically went the other way.
The UK/US gearbox differences arose because each meets the local requirements best, plus the familiarity factor. Had the UK, for example, gone down the 1950s US road of big V8s and straight 6s in a low state of tune while having huge local oil resources (the North Sea oilfields weren't being tapped back then) then maybe we'd also drive automatics and vice versa, but that didn't happen.
It's the same with operating systems. Historical familiarity counts for a great deal and favours Windows, and Windows, so long as the hardware is powerful enough, does a good enough job at many things. It's only people like us who want Windows to do things it wasn't designed for like low-latency audio that have to get involved in the inner workings. Windows great entry point into the home market was that for years and years you could borrow a set of Windows disks from work or a mate and install it on your own PC with no need to pay anyone anything at all. So people got used to Windows so choose Windows. And once a product has market dominance it has a huge advantage because people will tend to pick the market leader simply because the market leader "must be the best, right?"
Whether Windows would do as well if it went to a rental model is an interesting question. Personally I have my doubts. I'm not sure people wanting a computer at home would choose another OS instead though, I suspect they may simply cease buying desktop computers and switch to iOS/Android tablets which can already do a great deal of what home PC owners mostly want to do apart from resource-hungry games.
The corporate world may or may not stick to a rental Windows. That would be down to cost/benefit analysis, but the "MSDOS/Windows PC in every home" market Bill Gates talked of years ago might cease to exist.
