Microsoft has once again asserted that 1.5 billion PCs around the world run on Windows.
It posts the figure in its newly updated Microsoft by the Numbers website, which also shows off that Cortana has been asked 18 billion questions, facts about the company's artificial-intelligence activities, donations, and its carbon footprint.
The number is consistent with figures that Microsoft has previously set out about Windows adoption. Apple has about 1.3 billion active iOS devices, while Google reports about two billion active Android devices.
Microsoft in July said just under 700 million PCs are running Windows 10, up from 500 million in May. Last week, the company boasted that more than half of Windows devices in the enterprise are running Windows 10.
Microsoft's own app data statistics report shows that, as of September, 76 percent of all Windows PCs are running the Windows 10 April 2018 Update, version 1803, with the remainder on some earlier version.
Missing from the new By the Numbers report is a mention of Office. Previously it stated that Office apps have had been downloaded over 100 million times on Android and iOS, as Neowin reported when Microsoft's site launched in 2015.
