Windows 10 Build 14383: 1st RC for Anniversary Update

Microsoft has released Windows 10 Build 143834 a couple of hours ago for Windows Insiders in Fast Ring. This is the first release candidate (of probably many following builds). And there is a clarification from Donar Sarkar, that free Windows 10 upgrade doesn’t ends at 7/29/2016 for all devices.


Microsoft has announced the new build for desktop systems and mobile devices within the Windows-Blog, where also Vuong Chung from Vietnam is presented as the winner of the Continuum app contest from last week. But the more interesting news: On desktop systems (aka PC) the watermark in the lower right corner is gone. This is because Microsoft beginning to check in final code in preparation for releasing the Windows 10 Anniversary Update. 

Improvements and fixes

Microsoft has announced a long list of fixes and improvement for PC build.

  • The link to “Get more extensions from the Store” under the Extensions pane in Microsoft Edge now takes you directly to the Store to download available extensions.
  • Microsoft changed the keyboard shortcut to invoke Cortana in listening mode to Win + Shift + C based on feedback from Insiders experiencing a large number of unintended activations of Cortana while in listening mode. Speaking “Hey Cortana”, when enabled in Cortana Settings, continues to invoke Cortana in listening mode as it always has.
  • Going forward from this build, updates to the Quick Action area of Action Center will be preserved across upgrades.
  • Microsoft fixed an issue where disconnecting the Surface Book from an external monitor set as primary might result in the Surface Book screen showing in portrait rather than landscape until having detached and reattached the screen.
  • Microsoft fixed an issue where the Settings app was showing media controls in the taskbar preview window.
  • Microsoft fixed an issue where dragging the file comparison or manage library dialogs between two monitors with different DPIs would result in the dialog content no longer displaying correctly
  • Microsoft fixed an issue where the checkmark used to indicate a selected state in app bar toggle buttons wasn’t visible in high contrast, for example in the Photos menu under “…”.
  • Microsoft fixed an issue where connecting to a PC using Remote Desktop when a maximized window is immediately behind the Remote Desktop dialog would result in the subsequent the Credential UI window being displayed behind the maximized window.
  • Microsoft fixed an issue where, with certain monitor configurations, Explorer.exe would hang after a tooltip is displaying.
  • We fixed an issue resulting in certain Bluetooth mice, such as the Microsoft Arc Touch Mouse, sometimes accelerating erratically when moving the cursor across the screen.
  • Microsoft fixed an issue where on certain webpages in Microsoft Edge when Narrator was in Scan mode and going line by line through a list of hyperlinks, Narrator wouldn’t announce the fact that these were hyperlinks.
  • Microsoft fixed an issue with certain websites potentially causing a memory leak and becoming unresponsive in Microsoft Edge when the LastPass extension had been enabled.

There are also some fixes in Windows 10 mobile build that may be read here (I haven’t a Windows 10 capable mobile device).

Known issues for PC

There are two things, you should know. First of all, there is

a notification pop-up once a day that started on 7/1 saying that your Windows evaluation copy expires on 7/15/2016, don’t worry – this is a superfluous dialog and your OS won’t expire. The dialog will also go away soon. I’m wondering who has implemented this into the build.


Also Hyper-V machines with Windows Server 2016 Tech Preview 5 won’t boot in Secure Boot-Mode due to a bug in Hyper-V firmware. The workaround is to disable Secure Boot during this period.

BTW: Free Windows 10 upgrade won’t end 7/29/2016 …

for Windows Mobile devices. For PC the free upgrade ends at 7/29/2016 – but Windows Mobile devices will receive free Windows 10 Mobile upgrades after this date. Donar Sarkar has clarified in a Tweet

Well, for me it doesn’t matters. I haven’t no mobile devices capable of Windows 10 Mobile (as I wrote above). And for desktop Windows Insiders are able to continue testing new Builds after 7/29/2016.

Changes in Windows MVP program

Personally I have been transferred at 7/1/2016 from “Windows Consumer Experience” MVP (which has been cancelled) to the new Windows Insider MVP program. As I read “between the lines”, many of my Ex Windows Consumer Experience MVPs will take this transfer with a grain of salt. But we will see, what’s in the bag …
