Microsoft is currently working on the next major update to Windows 10, which is codenamed Redstone 2 and yesterday, the company has released Build 14915 for PC and mobile devices, but which came with a number of bug fixes and performance improvements. However, according to Twitter user “Core”, Microsoft will introduce a “BlueLightReduction” setting which will be toggled from the Action Center. For now, this feature is inactive and hidden, but it will be enabled once the Redstone 2 update will kick in.
Build 14915 brought bug fixes for Cortana’s text-to-speech functionality and it solved compatibility issues related to Yahoo Mail, Google, and Skype Translator apps. Also, the power button can be now used from the Start Menu, the Settings app will no longer crash on when navigating to different settings pages, the Connect flyout has been updated, so that the clickable area for each device listed now spans across the full width of the flyout and users can now select all text (using CTRL + A) in Microsoft Edge and paste it into Notepad. Also, there was an issue with ring settings that didn’t work when changing functionality via Settings > Update & security > Windows Insider Program, and Microsoft has fixed this.
Some of the fixes for mobile devices are for: the issue that caused applications to get stuck in a pending state when moving them between a SD card and internal storage; the issue that prevented Continuum-capable devices to connect to a previously paired Windows 10 PC; the issue that caused subsequent downloads in Edge to be saved to the default locations, instead of being saved in the preferred locations set under Settings > System > Storage. The “You need to fix your MSA” notification toast logic has been updated and it will no longer notify users multiple times in quick succession.
As for the “BlueLightReduction” setting, it’s similar to F.lux or Apple’s own native toggle that was introduced in iOS 9. Microsoft is reportedly testing this feature, and hopefully, it will be ready until the next update will be released next year.
