New builds of the Windows 10 OS currently in development are becoming as predictable as Microsoft's Patch Tuesday. Last Thursday, Microsoft released Build 10162 to its Windows Insiders in the Fast Ring, and like clockwork we have the latest Build 10166 this Thursday. It features the typical bug fixes and updates, but it also includes one special feature that not everyone will get to try out.
The primary feature of this update is the ability to purchase paid Wi-Fi through the Windows Store using the Microsoft Wi-Fi app. Currently, the option only works if you live in the Seattle area, but Microsoft plans to expand it to the rest of the U.S. soon.
It's likely that Microsoft will be working to get the service up and running online in other major cities preceding the release of Windows 10, and then work to expand to less populated areas thereafter. Currently, we have no idea what method it is using to transmit this Wi-Fi signal, be it municipal ground hotspots, satellite, balloon Wi-Fi transmitters similar to the ones Google is developing, or another method entirely. As a result, it's hard to say how long it will take this service to grow.
Developers on Windows 10 can look forward to this build too, as a new Windows 10 SDK was released alongside it. The SDK features new bug fixes and general improvements, as well as updates the Windows.ApplicationModel.Email function. Microsoft advised developers to uninstall the older 10158 SDK and emulators prior to updating, to avoid issues.
If you are interested in trying out the latest build and bug fixes, it is available now, but don't be surprised if another new build soon follows.
