Yeah, they were always talking about "total devices", meaning Windows phones/tablets, Surfaces, laptops, in addition to their traditional mainstay of home and business desktops.
It _IS_ a lot of machines. No question about it. But the trend is not great. Look how many Windows 7 machines they have to still convert, to swap places:
Those curves are nearly flat -- Win7 at just below 50%, Win10 at about 25%. They still have to convert at least half of the remaining Windows 7 machines to Windows 10. At the rate of the past half year, it'll take until long after Win7 is dropped from support (Jan 2020) to make that happen.
The above curves were snapshotted from NetMarketShare's site a few minutes ago.
I had no idea there were that many W7 machines out there!
I’d guess the bulk of them are POS systems. I’ll poke around a bit.
The’ll force the enterprise users to W10. It will happen soon enough.
Of course the punchline is if you’re losing to yourself you’re not really losing. All those Win7 boxes hanging around means they’re still selling Office and anybody that wants to actually make money selling software needs VS.
