Windows 10 PC and Mobile preview build 14376 released for Fast ring Insiders

Microsoft has released the Windows 10 PC and Mobile preview build 14376 to members of the Insider program on the Fast ring.

This new preview build is mostly for bug fixes and improvements for both the PC and Mobile versions of Windows 10. Windows Insider head Dona Sarkar has posted what's been fixed on the PC side:

• We're rolling out an Store update (11606.1001.25) that improves performance and reliability and includes fixes for accessibility as well.
• Clicking on networks or VPN connections in the network flyout on the taskbar should now launch the network settings page like it should. We also fixed an issue where the network flyout would sometimes only show the network settings link, despite being currently connected to Wi-Fi.
• For my dev peeps: we fixed the issue causing an error message when you enable Developer Mode due to the necessary package needed from Windows Update not being published appropriately. Go forth and create!
• We have updated Narrator to now support using physical volume buttons to adjust the volume while Narrator is in Scan Mode. We also fixed an issue that could result in Narrator crashing when arrowing through list entries.
• We have updated Windows Hello on the Lock screen to not repeat the name of the person logging in, when it is already displayed on the screen.
• We have fixed an issue where you might be unable to type in some UWP apps. We also fixed an issue resulting in certain Polish characters being duplicated when typed into UWP apps.
• We fixed an issue where the Lock screen background might not be displayed correctly.
• We fixed an issue where your password would revert be being hidden if you tried to edit it while holding the reveal button.
• We fixed an issue where the search dropdown in the Settings app could end up displaying above the search box instead of below it. We also fixed an issue where the "For developers" settings page would be blank while checking for an optional package, and an issue resulting in no handwriting, speech and other optional components being listed for languages that do support them.
• We fixed an issue that could result in not being able to turn on "set time zone automatically".
• We fixed an issue where the icons in some Start menu tiles could appear zoomed in, for example Alarms & Clock app or Calculator app.
• We have improved the consistency in scrolling and zooming speeds between monitors when using a precision touchpad on a multiple-monitor setup.
• We fixed an issue that could result in Explorer.exe crashing after receiving a notification from Microsoft Edge.
• We fixed an issue where the caret might jump to the beginning of the line, rather than maintaining current y axis position when using the up and down arrow keys in a textbox in Microsoft Edge.
• We fixed an issue resulting in an authentication error when launching mstsc.exe from an elevated Command Prompt.

There are no known issues with the Windows 10 PC preview build 14376. On the Windows 10 Mobile side of things, here are the bug fixes and improvements:

• We're rolling out an Store update (11606.1001.25) that improves performance and reliability and includes fixes for accessibility as well.
• The Gadgets app has been updated to fix issues using it with a Microsoft Display Dock.
• We fixed an issue that could result in tiles pinned to Start from within an app being blank after a restore. We also fixed an issue that could result in multiple Live tiles no longer updating until the phone had been rebooted.
• We fixed an issue making it difficult to download certain offline maps via Settings > System > Offline maps, as the list would jump back to the top when you reached close to the bottom.
• We fixed an issue resulting in the Camera app intermittently freezing for a second when used in certain apps.
• We fixed an issue resulting in links no longer working in Microsoft Edge after exiting one-handed mode while a webpage is loading. We also fixed an issue where the enter key would act as if it had been pressed twice on some websites, resulting in two new lines being entered.
• We have improved the reliability of going between camera roll and Camera app.
• We fixed an issue where estimated time remaining for battery life under Settings > System > Battery could be clipped. We also improved performance of enumerating the list of apps in under Settings > System > Storage.
• We fixed an issue where the link in Cortana to download a speech language would open the Settings app homepage instead of going directly to Settings > Time and language > Language.
• We fixed an issue where the checkmarks in checkboxes in high contrast mode didn't use the correct contrast ratio making them difficult to see.

Here are the known issues with the Windows 10 Mobile preview build 14376:

• You can open PDFs in Microsoft Edge but won't be able to use touch to interact with the PDF (such as scrolling, pan or zoom). When you try to use touch to interact with a PDF, it will constantly reload the PDF.
• We've heard you and we are investigating decreases in battery life on older devices such as the Lumia 830, 930, and 1520.
• We're also investigating Wi-Fi disconnect issues – if you are experiencing an issue with your Wi-Fi disconnecting, please see this forum post and make sure to upvote Wi-Fi disconnecting issues in the Feedback Hub.
• We have changed the backup format for Windows 10 Mobile devices to reduce the size of the backup stored in OneDrive. As a result, if you do a backup on a device running the latest Windows 10 Mobile Insider Preview builds and move back to the released version of Windows 10 Mobile (Build 10586) and restore from your backup – your Start screen layout won't restore and remain the default Start layout. Your previous backup also gets overwritten. If you need to go back to Build 10586 temporarily, once you are on Build 10586 you should disable backup so it doesn't overwrite the good backup from Windows 10 Mobile Insider Preview builds.
