Microsoft CEO Satya Nadella announced that Windows 10 has reached 500 million monthly active devices during his opening keynote at Microsoft Build.
With Windows 10, Microsoft put a strong emphasis on cross-platform functionality by debuting Universal Windows Platform apps, which work across multiple Microsoft product types — PC, tablets, smartphones, Xbox One and mixed reality, among others — using nearly identical code.
Additionally, the company revealed it now has 100 million monthly active users of Office 365 and 141 million monthly active users for its AI Cortana — though it should be noted this includes not just voice but also typing commands.
Building on that momentum, Microsoft also announced partnerships with HP and Intel for future Cortana devices and the opening of the public preview for its Cortana Skills Kit.
