Today for the first time since the Windows 10 Insider programme started Microsoft have released a new build of Windows 10 for the PC and phone at the same time. For the PC there is 14271 and for the Lumia 550, 950 and 950 XL is there 14267.1004.

14271 for the PC doesn’t have any new features but it does include plenty of fixes and some minor enhancements:

Here’s what’s fixed for PC

We fixed an issue where the window borders on apps would change from accent color to black after every upgrade to a new build.

We have updated the music control icons that are shown in taskbar previews in music apps like Groove to look more crisp and clean at higher resolutions.

We fixed an issue where the taskbar would sometimes not auto-hide and show unexpectedly on top of full screen windows such as showing above a PowerPoint presentation when in slideshow mode.

We fixed an issue where the “Hide notifications while presenting” setting preference is lost after upgrading to a new build.

The entire app header in Action Center is now right-clickable instead of just the app name or “x”.

We made it easier to dismiss all notifications from a specific app in Action Center by increasing the target area to encompass the entire app header.

We fixed an issue where interaction notifications would not show a button to input text in some cases.

Fast user switching should work now with Picture Password.

We fixed an issue where some desktop (Win32) apps look missing from Start.

We fixed an issue where the accent color does not automatically change when the slideshow option is chosen for your desktop background.

The issues with this release include an issue where the PC will not resume correctly from hibernation (this was problem introduced in the last build) and an issue with Kaspersky Anit-Virus:

Known issues for PC

We are tracking an issue reported by Insiders where some PCs will freeze or bluescreen when resuming from hibernation. Disabling hibernation is a workaround in some cases until this is fixed.

If you have Kaspersky Anti-Virus, Internet Security, or the Kaspersky Total Security Suite installed on your PC there is a known driver bug that prevents these programs from working as expected in builds from the Development Branch. We are partnering with Kaspersky to fix this issue for a future release, but at this time there are no known workarounds. While this issue is present, we recommend using Windows Defender or another third party anti-virus product of your choice to remain protected.

Turning on the “always show all icons in the notification area” setting disrupts the layout of the notification area (“systray”).

When browsing in Microsoft Edge, charts displayed using D3.js library will not display correctly – e.g. render as black, positioned incorrectly. Known affected sites are Cortana,, and

On the phone there is 14267.1004 a revision of the build from last week but with a fix for the Lumia 550 USB problem, the return of visual voicemail:

We fixed the issue reported by Insiders in Build 14267 where the Lumia 550 no longer charges or connects via USB. If you hit this issue on your Lumia 550 – we have laid out guidance on various methods to get back into a good state here.

We fixed the issue preventing Visual Voicemail notifications from happening.

We’re introducing Visual Voicemail for dual-SIM devices such as dual-SIM Lumia 950 XL! Work for this feature was in Friday’s release but due to the above mentioned bug impacting notifications it was not working correctly. But now the experience should be working as expected.

We’ve released an update to the People app that brings back the history feature. For a given contact you communicate with, you can view the interaction, whether by today, yesterday, last week etc. Right now, your Skype messages won’t show up in history yet but we’re working on enabling this in a future update. Also – we’re tracking a bug in which opening an email item in history might not take you to that specific email.

Issues with this build include an issue with the trackpad when using Continuum and a problem with wireless displays.

Look out for hands on video with the PC and phone soon.
