Considering its free for practically everyone (really, who doesn't have a Win7/8/8.1 license somewhere around?), that doesn't seem to be a goal they are after.
I'm not entirely sure what they're after with the pricing model, however, I feel it is worth pointing out that upgrade revenue has always been a tiny sliver-of-a-fraction of the overall Windows revenue pie. Almost no one upgrades. Yes, us nerds do it, but we are
few.
Everyone else only gets new editions of Windows when they buy a new PC.That doesn't mean it doesn't impact the revenue picture (even ignoring upgrades,
some people buy new PCs, primarily to get the new version of Windows, though those people are also probably few). But still... There are a ton of people who probably have a qualifying license for Windows 10, and still won't upgrade. Microsoft sure seems to be pushing it this time around (with the little white flag you can't make go away unless you're a nerd), but...
I don't know. It is still an overall small piece of the pie. Suffice to say, I don't know what they're up to this time. I don't even know for sure if
they know.
