SAN FRANCISCO—Windows 10 was the focus of Microsoft's day one keynote at its annual Build developer conference. Today, the company announced an update that'll ship this summer called the "Anniversary Update."
The company led by talking about the adoption of Windows 10. After its first eight months on the market, there are now 270 million Windows 10 users. This is immensely fast for a new Windows version, with Microsoft claiming that Windows 10 adoption has outpaced Windows 7 adoption by 145 percent.
Still, Microsoft has a long way to go to hit its target of 1 billion Windows users within two years of launch. Windows 10 will continue to be a free update for Windows 7 and 8 users for another 4 months, after which time anyone on those operating systems will, in principle, be required to pay. We can well imagine that Microsoft will extend the promotion in some way, but the company hasn't announced any plans to do so just yet.
