After a long wait, Microsoft finally rolled out a new Windows 10 Redstone 2 build to Windows Insiders in the Fast Ring. As always, build 14915 for both PC and Mobile brings many fixes and improvements as well as a new feature for PC. This is the first Redstone 2 build that has introduced new features as the first two builds focused only on fixes.

Build 14915 now allows Windows 10 PC users to download OS and app updates from other computers on the internet. Thanks to this new feature, the internet bandwidth usage required for updates can be reduced by up to 50%. The Delivery Optimization feature is turned on by default, but users can disable it at any moment by going to Settings > Update & security > Windows Update > Advanced options and choosing Choose how updates are delivered.

Build 14915 brings 11 fixes and improvements for PC and 9 for Windows 10 Mobile. Insiders can now use the power button in the Start Menu on their PCs, and the Settings app should no longer crash that often. The Mobile fixes focus mainly on eliminating compatibility issues between the OS and various apps.

Here’s what’s fixed for PC

  • We fixed the issue with being unable to use the power button on the Start menu.
  • We fixed the issue causing Cortana’s text to speech capabilities to not work. […].
  • We fixed the issue causing the Settings app to crash on certain editions of Windows 10 when navigating to different settings pages due to a missing .dll file.
  • We made a number of improvements to translations […].
  • Changing functionality via Settings > Update & security > Windows Insider Program such as your ring settings should now work again on this build.
  • We fixed a compatibility issue from a recent platform change that causes apps such as Yahoo Mail, Trivia Crack, Google and the Skype Translator Preview app to crash.
  • We fixed an issue resulting in some Insiders experiencing a delay in Mail notification toasts appearing.
  • We fixed an issue where the “Open with” dialog’s “Look for another app on this PC” link wasn’t working […].
  • We have updated the Connect flyout so that the clickable area for each device listed now spans across the full width of the flyout.
  • We fixed an issue where if a Chinese Input Method Editor is active it could result in logging in to not succeed after device goes into and is woken up from Connected Standby.
  • We fixed an issue where for certain websites in Microsoft Edge, using CTRL + A to select all text and then copying it and trying to paste it into Notepad wouldn’t paste anything.
  • We fixed an issue where importing favorites into Microsoft Edge from Internet Explorer would fail if the Favorites folder had been redirected to another folder, for example “C:\Users\\Documents\Favorites”.

Here’s what’s fixed for Mobile:

  • We fixed the issue causing apps to get stuck in a pending state if you move apps between a SD card and internal storage (either direction).
  • We fixed the issue causing Cortana’s text to speech capabilities to not work. […].
  • Changing functionality via Settings > Update & security > Windows Insider Program such as your ring settings should now work again on this build. 
  • We fixed a compatibility issue from a recent platform change that causes apps such as Yahoo Mail, Trivia Crack, Google and the Skype Translator Preview app to crash.
  • We made a number of improvements to translations […]
  • We have updated “You need to fix your MSA” notification toast logic, so it will no longer notify you multiple times in quick succession.
  • We fixed an issue where examining Microsoft Edge’s advanced settings would result in subsequent downloads in Edge saving to the default locations, rather the preferred locations set under Settings > System > Storage.
  • We fixed an issue for Continuum-capable devices that could result in being temporarily unable to connect to a previously paired Windows 10 PC.
  • We have updated the settings for sounds so that .mp3 or .wma files downloaded straight from OneDrive or copied from File Explorer to the phone’s Ringtones folder will now display automatically in the list of available sounds for ringtones, alarms and notifications.

Build 14915 is not a bug-free build, as Insiders may encounter Adobe Acrobat Reader crashesblack screens when signing out and switching to another user account, and a non-working Bash after upgrading to this build. Unfortunately, the Settings app may crash when going to Settings > Personalization. Windows 10 Mobile users won’t be able to download and install additional speech and language packs in this build.
