Microsoft has released another Windows 10 Insider Preview build as the release pace continues to pick up with its release on July 29. Windows Insiders can download Build 10166 right away and it brings with it a range of bug fixes and fit-for-finish features, plus something exclusive to customers in the Seattle area to experiment.
Microsoft plans to test the feature out close to home and then roll it out to the rest of the US in due course, although with free Wi-Fi widely available it's unclear how popular the feature would be.
