Windows 10 Mobile now on nearly 5 percent of all Windows Phones

In this month's AdDuplex report, a surprising increase in devices running Windows 10 Mobile has been confirmed with 4.7 percent of all devices running the new OS. The numbers reflect a 1.4 percent increase from last month and strongly suggests that more users are taking advantage of Microsoft's free Insider preview program.

Windows 10 Mobile is expected to be released next month after Microsoft's New York City press event on October 6. Those who are part of the Insider program will get the update first before carriers begin to provide officially over-the-air updates. Additionally, new hardware running Windows 10 Mobile should be in people's hands by early November.

What to expect from Microsoft's Windows 10 devices event in NYC

The increased adoption of Windows 10 Mobile – even in beta form – is likely due to the growing stability of the OS making it more appropriate to use on people's daily phones. Microsoft still likely has a few builds before the OS is "finalized" for the actual release, however, meaning there is still more to come.

Nonetheless, even with Windows 10 Mobile becoming official, the Insider program is going to continue. Those enrolled today will carry on receiving Insider previews as Microsoft's Windows as a Service (WaaS) treatment of the mobile OS takes off.

The conclusion that can be reached is the Windows Insider program – even for mobile – is a general success for Microsoft. Having such a large swath of users with Windows 10 Mobile is likely providing the software company with a lot of telemetry data that will be used to continue to improve the OS over time. Having said that, most users would likely agree that Microsoft still has many obstacles to overcome before even their most ardent fans are convinced Windows 10 Mobile is worth their trouble.
