Microsoft said more than 200 million monthly active devices around the world are using its Windows 10 platform, with initial demand for the first smartphones running the platform outstripping supply.

Initial volumes have obviously been driven by Microsoft’s PC activities, aided in no small part by the free upgrades it is offering users of some existing platforms. But nonetheless, this has enabled it to generate some momentum for the OS, with Yusuf Mehdi, corporate VP in the Windows and Devices Group at Microsoft, stating that this is “the fastest growth trajectory of any version of Windows – ever”.

The company previously gave a figure of 110 million, which was revealed in October 2015.

With Microsoft having struggled in the mobile space, in no small part due to a perceived “app gap” between Windows Phone and iOS (Apple) and Android, it is positioning Windows 10 as a way for developers to reach PCs, tablets, phones “and more” – and swiftly reaching 200 million users will help draw them toward the platform.

It said has seen 3 billion visits to its new, single Windows Store for apps, with more universal apps becoming available for the platform. While this is obviously focus on PC and tablet users, it will also help strengthen the catalogue for its mobile users – although the company may still struggle bringing mobile-only/mobile-first apps to the platform.

So far, Microsoft’s Windows 10 efforts in the mobile market have been limited, with the focus on its Lumia 950 and Lumia 950 XL smartphones. Mehdi said that these are “now available worldwide and off to a great start, with initial demand outstripping our supply”.

Of course, this does not give much detail on how the device is performing in comparison with rivals, or with earlier Lumia devices, but with Microsoft often lacking wins in the mobile market, it is understandable it is highlighting its positives.
