Microsoft has released a new preview build of Windows 10 for both PC and Mobile for members of the Insider program in the Fast Ring. The new build number for the preview versions is 14267.1004 for Mobile and 14271 for PC users.
Microsoft's Gabriel Aul stated:
"This will be the first time we release builds for PC and mobile on the same day. For PC, Build 14271 brings a lot of improvements and bug fixes that are based on feedback we have received from Windows Insiders."
"Starting with Build 14271 and newer, the frequency in which Windows will ask for your feedback will be locked to "Automatically (Recommended)" in the Settings app and managed by the Windows Insider Program. If having the ability to change this setting is important to you – you can roll back to the Windows 10 November Update (the latest build or future builds in our Current Branch) and disable Windows 10 Insider Preview builds on that device. You will then be able to change this setting. While we don't require Windows Insiders to answer these questions, we do hope they take the time to answer them so that we can better improve Windows for our customers."
