Yesterday Microsoft released Windows 10 Insider Preview Build 14959 for Mobile and PC to Windows Insiders in the Fast ring.
The Windows 10 Creators Update
Last week, we held an event in New York to share our aspiration to empower a new wave of creativity with the Windows 10 Creators Update and new devices such as the Surface Studio and Surface Dial. You can catch up on all the details on the things we announced at the event by checking out this blog post from Terry Myerson. As I mentioned last week, Windows is an iceberg, the features that people “see” are quite a small percent of the engineering work that we do to enable new UI to be visible. Windows Insiders running the latest builds have already been trying out the Creators Update – including last week’s build (Build 14955). The new and exciting visible features you saw shown off at the event will start rolling out in builds in the coming weeks. Features such as the Paint 3D Preview are now available for Insiders to try right now! We’re excited to get more of the new Creators Update features in the hands of Insiders in the next couple of months.
What’s new in Build 14959
Unified Update Platform: This build for Mobile is being published using our new update publishing system called Unified Update Platform (UUP). For more information on UUP – check out this blog post from Bill.
Controlling the Display Scaling of your Virtual Machines (PC): We’ve heard your feedback that Hyper-V Virtual Machines sometimes aren’t scaled as you’d expect, so we’ve added a new Zoom option in the View menu, where you can override the default scaling and set it to 100, 125, 150 or 200 – whichever matches your preference. Along the way, we also fixed an issue where certain VMs wouldn’t display the remote desktop connection bar after entering full screen mode. We are still refining the experience so there might be some rough edges. For example, although we added zoom levels to handle high DPI more gracefully, when zooming you won’t be able to see the VM’s whole screen without scrolling.
Other improvements and fixes for PC
- We fixed an issue for Insiders resulting in the automatic brightness setting unexpectedly being turned off after upgrading. In doing so, we’ve re-enabled automatic brightness adjust for users that have never changed their auto-brightness setting. If you have already manually configured your auto-brightness setting, then this fix will not affect you. If you would like to enable or disable automatic brightness adjustment, please go to Settings > System > Display, where you can adjust your preferences.
- We fixed an issue Insiders on domain connected PCs may have experienced where login might fail when the computer was disconnected from its domain network.
- We fixed an issue resulting in certain apps, such as Outlook Mail and Calendar, failing to update for some Insiders with the error code 0x800700B7.
- We fixed an issue for Insiders with certain device models where ejecting an SD card might result in a system crash.
- We fixed an issue where disliking one of the Spotlight lock screen images would show the new image immediately, followed by a transition animation from the previous image to the new image.
- We fixed an issue where launching an app from another app while in Tablet mode no longer launched it side by side, and instead launched it fullscreen (for example, when launching a web link from the MSN News app).
Other improvements and fixes for Mobile
- The data usage page in Settings via Settings > Network & wireless > Data usage has been updated with performance and UI improvements.

- We fixed issues preventing Insiders from adding cards to Wallet and paying using tap to pay.
- We fixed an issue resulting in being unexpectedly able to close Start in the task switcher.
- We fixed an issue resulting in certain options for default calling app via Settings > System > Phone > Default apps from being unexpectedly missing.
- We fixed an issue causing apps that play media in the background, such as Groove Music, to stop when Battery Saver turns on.
- We fixed an issue Insiders may have experienced where the phone would get into a state where copy/paste wouldn’t work until the device had been restarted.
- We fixed an issue where Settings might hang after unchecking “Let apps automatically use this VPN connection” in VPN Settings.
Known issues for PC
- If you have a 3rd party antivirus product installed on your PC – your PC might not be able to complete the update to this build and roll-back to the previous build.
- We’re aware of an issue where Internet Explorer may crash a few seconds after launch and working.
Known issues for Mobile
- If you used the previous ‘date change’ workaround to update to Build 14951 or Build 14955: Please don’t use it any longer! The Microsoft account (MSA) ticket on your device needs to expire and then you’ll be offered today’s build. If you changed your date by 30 years… you’ll want to do a device reset.
- You will be unable to install additional languages, keyboards, and speech packs on your phone for the next few weeks. If you have existing languages, keyboards, and speech packs installed – they will carry over when you update to new builds. You just can’t install any new ones. If you do a hard reset of your phone on these builds – you will also be unable to install additional languages, keyboards, and speech packs. You can use Windows Device Recovery Tool to go back to Windows Phone 8.1 or Windows 10 Mobile, install any languages, keyboards, and speech packs you need and then update to the latest build in the Fast ring as a workaround.
November 2016 Bug Bash begins next week!
We are moving the Bug Bash start date up to Monday, November 7th 12:01 AM PST. We wanted to give you, Windows Insiders, and our Windows Engineers the same dates for finding bugs (in the past our engineers started a day early)! We will start the Bug Bash on Build 14959 that is being released today so you can have time to get your PC’s and phones updated prior to the Bug Bash so you can start Quests as soon as they are published. The Bug Bash will still finish at the end of the day on Sunday, November 13th (PST). Our whole team will be bug bashing with some fun events in-house and we are looking forward to seeing a lot of participation from Insiders!



We are also introducing Stencils. Windows Ink protractor tool combines functions of both protractor and compass into one – now you can draw an arc or a complete circle of an arbitrary size with little effort. A familiar two-finger pinch gesture resizes the protractor to the desired size and a degree readout follows your pen, mouse, or finger as you draw along the side of the protractor displaying arc degrees. In this preview build, ruler also got a small update – its degree readout shows a numerical value of the angle, making drawing angles even easier.
Simplified, more familiar camera interface (PC & Mobile): The Camera app received a big update this week for Insiders. We’ve redesigned the Camera interface for ease and accessibility. Check out some of our new features:
You can now experience the magic of living images on your Surface, now enabled on Surface Book, Surface Pro 4, Surface Pro 3, and Surface 3! With living images, extend your still captures with a snippet of video. These are created automatically whenever your shots feature motion—just navigate to Settings and turn on Capture living images.
Simplifying your developer experience (PC): We’ve done some underlying work, and now you’ll no longer have to reboot your PC after turning on Developer Mode! This means that you can start using Device Portal and Device Discovery as soon as the Windows Developer Mode package has finished installing, rather than having to reboot first.
However, we know that some of our Insiders prefer even more control over their experience, so for those Insiders (and power users) we have added a new Advanced Gestures Configuration page. The page can be accessed via a link at the bottom of Touchpad settings page.
The Advanced Gestures Configuration page has more configuration options, including hooking gestures up for next/previous song, creating/deleting virtual desktops, or snapping windows. In addition to these new options, we’ve also updated the Touchpad settings to include reference diagrams to remind you of what to expect when you swipe with three or four fingers in a particular direction.
We are also continuing to move functionality from the Wi-Fi (legacy) screen to the new Wi-Fi settings screen on Mobile. After you turn off Wi-Fi, choose a time under Turn Wi-Fi back on to have it turn on automatically after the amount of time you choose. Based on what we heard from customers in the Windows 10 Anniversary Update, we changed the default setting from “In 1 hour” to Manually in this build.
Photos app update: With the latest Photos app update on your PC, the Photos app on your PC is now more beautiful and easier to navigate!


Form field navigation in Narrator: We are excited to announce that this build introduces form field navigation to Narrator.
