After releasing Build 14926, Microsoft has rolled out a new upgrade called Windows 10 Redstone 2 Preview build 14931 to Windows Insiders on the Fast ring. This purportedly fixed bugs and problems found in the former build, which — for its part — is considered one of the most important builds since the Anniversary Update released last month.
The latest build is not introducing key features such as those implemented in Build 14926 but is rolling out fixes to problems including how some users see a black screen when signing out or the inability to login when switching to a different user account. The problem in opening built-in Windows app like the Alarms and Clock, Calculator and Voice Recorder applications has also been addressed.
Minor upgrades include an update to the Feedback Hub, which includes highly requested features such as dark mode, a setting page and the ability to show the original feedback author in the feedback details.
The Maps application has also been tweaked. Insiders are finally able to check traffic to Home and Work locations through the Traffic icon found in the app bar.
There is also the capability to send and receive SMS and MMS messages using the Skype Preview, which has been released in the previous build. This supposedly works for Skype in Windows 10 PC and when Skype is the default messaging app in a Windows 10 mobile phone.
Finally, the new build introduces native support for USB Audio 2.0. This covers devices with an inbox class driver.
Build 14931 is only available to PC users. The exclusivity has been explained by program lead Dona Sarkar.
"We are continuing to investigate two issues that came up with last week's flight of Build 14926 for Mobile," Sarkar said in a blog post. "After upgrading to Build 14926, some Insiders reported that the pin pad is no longer visible to unlock their phone even after rebooting the phone and some phones lost the ability to use their SIM card."
The two factors were said to be solved by a hard reset. But the problems, including the feedback gained from testers prompted Microsoft to refrain from releasing a build for mobile devices.
The Windows Insider program underscores how the Windows 10 OS is still currently under development. It was launched in 2015 but Microsoft is continuously improving it by testing and releasing new builds.
This is made possible by the fact that Windows 10 was built differently than previous releases. Particularly, its core upgrade mechanism technology allows developers to test builds and to implement them accordingly. This explains why users consistently receive improvements and new features in the form of patches and updates.
