It was only earlier this year that Microsoft boasted that there were over 500 million devices powered by Windows 10, but six months later the Redmond-based giant has added another 100 million users bringing the total to a whopping 600 million.
Microsoft CEO Satya Nadella announced the new figures during Microsoft's annual shareholders meeting today, missing the mark that they planned on reaching by 2018. Originally, Microsoft expected to have Windows 10 running on 1 billion devices, but is now 400 million - or 40%, short of that number.
The Verge report that Microsoft revised its numbers for Windows 10 installations, targeting 550 million active Windows 10 devices by the end of June, and 575 million by the end of September. This means reaching 600 million by the end of November is falling into line, but will there ever be 1 billion Windows 10 devices? If so, it won't be in 2018 at this rate.
