Last night Microsoft released another Build to the Fast Ring Insiders, Build 15058, another build without the build watermark on the lower right corner, we must be getting close to the Creators Update! Your 1607 (non-insider) Build is also showing a teaser in the update section:

Getting users to use Office more efficiently can be quite a challenge, these new courses can get them started easily:

Last Tuesday Microsoft released Windows 10 Insider Preview Build 15046 for PC to Windows Insiders in the Fast ring. This Build seems a lot more stable than the previous one… Enjoy upgrading!

As you can see, we have done quite a few experiments in the Creator’s Update so far to try out different colors and icons and we have loved co-creating the results you see today with you.

What’s new in Build 15046

Color of Cortana’s home on the taskbar: You had a LOT of opinions on this topic and we have been loving the enthusiastic feedback coming in! We finished our experiment with the color of Cortana’s home on the taskbar and for now, it’s back to the color it was before. Thanks for your feedback on this change.

Windows Defender Improvements: Windows Defender Security Center has added a notification icon to the notification area so you can see your protection status at a glance. You can also easily launch the app from the notification icon. Windows Defender Antivirus notifications also now lead to Windows Defender Security Center when clicked. Also: Windows Defender Security Center can now be launched directly from the Settings app and the “App and Browser” page is now functional.

Pick up where you left off in Cortana: We are experimenting with how we display what you can pick up where you left off across your devices in Cortana. Cortana now proactively shows you apps, files and websites from Microsoft Edge. Previously, this feature only displayed websites from Microsoft Edge in Action Center. Let us know what you think! (Available EN-US only.)

Improved translations: For Insiders who speak non-English languages, we wanted to let you know that we have heard your feedback on our translations and have been actively making improvements. With this build you should see improvements – particularly in OOBE and for some of our newer settings, but across the system as well. We encourage you to take a look around the system, and if you spot anything translation that doesn’t quite seem on point, please log feedback using the steps here.

Updated Gaming Settings icon: A lot of you sent in feedback on this. We listened and adjusted the Gaming icon in Settings to feel more inline with the other icons on the Settings home page.

Application Installation Control: You now have the option to control what type of apps are allowed to install on your PC. This setting is available by going to Settings > Apps > Apps & features. You can choose to only allow installation of Store apps, choose to be warned when installing a non-Store app but allow their installation, or choose to allow installation of apps from anywhere.

When you choose either of the Store options, you’ll see a warning when attempting to install a non-Store app. The warning will direct you to the Store where you can download an alternate app if available. In some cases, when there’s already an equivalent app in the Store, the warning will provide link to that app. This is an opt-in feature, and the default setting is to allow installation of apps from anywhere. (Note: This went live with last week’s build.)

Other changes, improvements, and fixes for PC

• We fixed the issue causing a small percentage of PCs to fail to update to recent builds due to a corrupt registry key.
• We fixed the issue causing Microsoft Edge and / or the taskbar to stop responding requiring you to open Task Manager to restart explorer.exe.
• Windows Hello face authentication should work again on Surface Pro 4 and Surface Book devices.
  After updating to a new build, we’ve updated the text on the welcome screen to say “Might take several minutes” instead of “Might take several minutes or so”. Thanks to everyone who sent feedback on how the original phrasing was overly casual.
• Cortana’s background is now black instead of the previous grey.
• We fixed an issue in tablet mode where, with certain DPI levels, Start tiles would render on first launch of Start after entering tablet mode but on subsequent launches would appear blank.
• We fixed an issue resulting in Shift+F10 not working to open context menus for websites displayed in Microsoft Edge.

• We fixed an issue resulting in Microsoft Edge launching on pen click when that was the configured pen click action in Pen and Windows Ink Settings.
• We fixed an issue resulting in Microsoft Edge sometimes unexpectedly crashing when deleting characters typed using an IME (for example, the Japanese IME, or the MS Pinyin IME).
• We fixed an issue resulting in drag and drop (for example, into an Outlook 2016 email) sometimes not working on PCs with multiple monitors where the two monitors have different DPIs.
• We fixed an issue where the icon for Windows Insider Program under Settings > Update & security was shown as a square.
• We fixed an issue where all windows on a PC using multiple monitors would move to the primary monitor after remoting into the machine from a single monitor remote desktop session.
• We fixed an issue resulting in Storage Sense in Storage Settings failing to purge the recycle bin with certain machine configurations.
• We fixed an issue resulting in an unexpected and unnamed 0 byte item listed under Manage Optional Features in Settings.
• We fixed an issue where PC Reset wasn’t working in the last flight, the PC would boot to a blue screen saying that there was a problem resetting your PC.
• We fixed an issue resulting in being unable to mount an ISO with the sparse file attribute set.
• We fixed an issue where handwriting text candidates might stop working properly after using strikethrough to erase words written in the handwriting panel.
• We fixed an issue resulting in the Korean IME’s composition indicator unexpectedly not appearing when typing jamo into certain text fields.
• We fixed an issue where app updates in the Store may fail with error code 0x8020002B.
• We fixed an alignment issue with entries on the Sign-in options Settings page.
• We fixed the issue causing the Microsoft Edge F12 Developer Tools to intermittently crash, hang, and fail to accept inputs. If you continue to have issues with the F12 Developer Tools, send us feedback!
• We fixed the issue where pressing F12 in Microsoft Edge multiple times invokes multiple F12 windows (all but one are non-functional).
• We fixed the issue where toggling F12 between the docked and undocked state repeatedly can crash Microsoft Edge.

Known issues for PC

• Some PCs will fail to update to this build at 71% and roll-back to the previous build. See this forum post for details.
• [GAMING] Some popular games might minimize to the taskbar when launched. You can click on the game on the taskbar to get the game back.
• [GAMING] Certain hardware configurations may cause the broadcast live review window in the Game bar to flash Green while you are Broadcasting. This does not affect the quality of your broadcast and is only visible to the Broadcaster.
• Some UWP apps may unexpectedly appear with their app package in the title bar as opposed to the app name.
• Pressing F12 to open the Developer Tools in Microsoft Edge while F12 is open and focused may not return focus to the tab F12 is opened against, and vice-versa.
• Sometimes launching F12 will launch the F12 window behind the active Microsoft Edge window.
• ADDED: Insiders with multiple monitors may encounter an issue where one of the monitors stops rendering (with the exception of the mouse). While rebooting will fix it, you can also resolve the issue via Settings > System > Display under the Multiple displays section, set it to only use the monitor that’s functional, then set it back to “Extend these displays” and the issue should be resolved.
• ADDED: Some Insiders are reporting getting an 0x80070228 error when attempting to download this build. See this forum post for details.

Hello Windows Insiders!

Today we are excited to be releasing Windows 10 Insider Preview Build 15042 for PC and Build 15043 for Mobile to Windows Insiders in the Fast ring. We have discovered a bug that impacts our ability to release this build to PCs running 32-bit (x86) versions of Windows 10 Insider Preview builds. Because the majority of Insiders in the Fast ring have PCs running 64-bit (x64) – we decided to go ahead and release this build with 32-bit PCs blocked until our next flight. Also – please read the known issues below.

What’s new in Build 15042

New Cortana animation in OOBE (PC): We know how much you love animations, so we wanted to share with you our updated Cortana persona that you’ll see when you land on the Cortana page in OOBE:

Prompt to enable Flash in Microsoft Edge (PC): Back in Build 15002, we introduced click-to-run Flash by default in Microsoft Edge, for better security and performance across the Web. In today’s build, we’ve added a new dialog in the URL bar to make it clearer when Flash content has been blocked. Just click the puzzle icon to allow Flash once or every time you return to the same site.

Improved reading experience with Microsoft Edge: You loved the new Edge reading experience and gave us a TON of feedback. Here are some we implemented:

• When reading a locally saved EPUB book in Microsoft Edge on PC, a book icon will now be used in the place of the previous generic in the tab bar.

• If you switch pages while an EPUB book is being read aloud in Microsoft Edge, the reader will now jump to that new location in the book.
• If you’ve changed the read aloud settings when reading an EPUB in Microsoft Edge, those settings will now be preserved for subsequently opened books.

Other changes, improvements, and fixes for PC

• You should no longer see “Initializing…” when attempting to download new builds.
• The download progress indicator shown when downloading new builds under Settings > Update & security > Windows Update should be working as expected and it should no longer appear you are getting stuck at 0% or at other percentages.
• We fixed the issue causing the Settings app to crash when navigating to Settings > Devices and you should be able to pair a Bluetooth device without any issue. The Bluetooth quick action from Action Center should also now work again. This issue may also have resulted in generally decreased reliability in the quick action section of the Action Center.
• You should be able to launch the Connect UX via Action Center, Win + K, or Settings again.
• We fixed an issue where under Settings > Update & security > Windows Update Insiders might see the text “Some Settings are managed by your organization” even though the PC wasn’t being managed by an organization.
• We fixed an issue resulting in the Action Center sometimes appearing blank and transparent without color.
• We fixed an issue where upgrading with an Xbox controller paired over Bluetooth could result in touch input not working and unexpected beeps when using the mouse.
• We fixed an issue where items displayed in the autocomplete dropdown when filling form fields in Microsoft Edge would not insert when clicked.
• We fixed an issue resulting in images unexpectedly being missing from certain PDFs when viewed in Microsoft Edge.
• We fixed an issue resulting in web notifications not launching the associated website in Microsoft Edge after being clicked.
• We fixed an issue from recent flights resulting in some downloads from Microsoft Edge unexpectedly getting stuck in the “Waiting to download” state.
• We fixed an issue where the preview thumbnails for certain websites appeared blank as they were taken before the webpage ran its JavaScript / Ajax to fully draw its layout.
• We fixed an issue where the calculator button on the keyboard wouldn’t work if Microsoft Edge was in focus.
• We also fixed an issue where Win + Shift + left/right arrow wouldn’t work on Microsoft Edge after selecting text on the open website.
• We fixed an issue where pressing Alt + C with text selected in Microsoft Edge didn’t open the Cortana pane on recent flights.
• We fixed an issue resulting in Microsoft Edge not being able to open the file:// protocol with the AdBlock Plus extension enabled.
• We fixed an issue where in Microsoft Edge, if you were already on a website associated with an app, clicking a link on that website to go somewhere else on the website’s domain would unexpectedly launch the associated app.
• We fixed an issue resulting in not being able to insert words into certain text fields in Microsoft Edge when using the handwriting panel to enter text.
• We fixed an issue resulting in the password placeholder text being unexpectedly shifted down in certain password text fields in Microsoft Edge.
• The new Share icon is now visible in Microsoft Edge and the Windows Ink Workspace Sketchpad and Screen Sketch.
• We fixed an issue we certain devices on recent builds where resuming from hibernation could result in a bug check.
• We fixed an issue where sometimes a single notification toast might not pop up, only to be unexpectedly found duplicated in the Action Center.
• We broadened our recent fix for an issue that had some PCs with older graphics chipsets seeing white or colored boxes in the place of text and some UI elements in UWP apps to cover more hardware.
• If you right-click an app suggestion in Share, you’ll now find a context menu option to turn them off.
• We fixed an issue where ink would go under the Windows Ink protractor when inking with the highlighter.
• We fixed an issue where the first ink stroke into the Windows Ink Workspace Sketchpad wouldn’t enable the clear all button.
• We fixed an issue where the sample ink stroke seen in the Windows Ink pen, pencil and highlighter flyout would appear to blink when the flyout was first opened.
• We fixed an issue that could result in the new XAML scrollbar animation (as seen in Settings) becoming stuck in the transition state.
• We fixed an issue resulting in “Microsoft Camera Front” and “Microsoft Camera Rear” unexpectedly showing up, with barcode scanner icons, as optional devices to connect to in Devices Settings on Surface Books.

• We fixed an issue where the bug check screen on high resolution displays wasn’t rendering the “Frowny” part of the frowny face.
• We fixed an issue where night light might not turn on/off automatically if the device was asleep at the time at which the night light state was scheduled to change.
• The night light on/off animation’s duration has been increased to 2 minutes – appreciate everyone who’s shared feedback for this feature, keep it coming!
• Microsoft Edge’s “Inspect Element” and “View Source” options should launch correctly to the DOM Explorer and Debugger, respectively.

Other changes, improvements, and fixes for Mobile

• We fixed the issue causing the Settings app to crash when navigating to Settings > Devices and you should be able to pair a Bluetooth device without any issue. The Bluetooth quick action from Action Center should also now work again. This issue could have also resulted in decreased Flashlight quick action reliability.
• Using Continuum to connect to a display wirelessly should also work as expected.
• We fixed an issue resulting in screen rotation sometimes unexpectedly not working on the last Insider flight.
• We fixed an issue where live tiles were not updating some apps such as Outlook Mail and Calendar.
• We fixed an issue where under Settings > Update & security > Phone update Insiders might see the text “Some Settings are managed by your organization” even though the phone wasn’t being managed by an organization.
• We fixed an issue from recent flights where you couldn’t paste or drag a folder from the PC to your phone
• We fixed an issue where tapping the link for a website with an associated app would crash Microsoft Edge and not open the associated app.

• The icon for Windows Insider Program under Settings > Update & security should be no longer a square.

Known issues for PC

• A small percentage of PCs may fail to update to this build due to a corrupt registry key. If your PC appears to be at the spinning dots black screen during boot for an unusual amount of time while updating to this build, hard reboot your PC and then run the following commands in an admin Command Prompt:

  1 2 3 4 5

  reg delete HKEY_LOCAL_MACHINE\system\setup\upgrade\nsimigrationroot /f   netsh int ipv6 set locality state=disabled   reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nsi\{eb004a01-9b1a-11d4-9123-0050047759bc}\28 /f

  For more information on this issue, see this forum post.

• While we fixed the primary bug causing this issue, some Windows Insiders may still hit nonstop exceptions in the Spectrum.exe service causing their PC to lose audio, disk I/O usage to become very high, and apps like Microsoft Edge to become unresponsive when doing certain actions such as opening Settings. As a workaround to get out of this state, STOP the Spectrum.exe service and delete C:\ProgramData\Microsoft\Spectrum\PersistedSpatialAnchors and reboot. For more details, see this forum post.
• [GAMING] Some popular games might minimize to the taskbar when launched. You can click on the game on the taskbar to get the game back.
• [GAMING] Certain hardware configurations may cause the broadcast live review window in the Game bar to flash Green while you are Broadcasting. This does not affect the quality of your broadcast and is only visible to the Broadcaster.
• Microsoft Edge F12 tools may intermittently crash, hang, and fail to accept inputs.
• The icon for Windows Insider Program under Settings > Update & security is shown as a square.

Releases are so fast I did skip one on the site here, last week MS release 15025, yesterday 15031 was released to the Fast Ring lots of new stuff, take it for a spin!

if you are using ReamoteAPP be carefull with this one, they might stop working (connection fails)

What’s new in Build 15031

Do more at once with the new Compact Overlay window: Ever want to continue watching a movie while switching app to check your email? Or keep an eye on your video chat even as you’re browsing the web? We do all the time! Some tasks don’t require the user’s full attention but is perfect to leave at the corner of the screen so we’re introducing a new compact overlay mode for UWA app developers. When an app window enters compact overlay mode it’ll be shown above other windows so it won’t get blocked. The best part is that compact overlay windows work just like normal windows in all other ways so app developers can tailor the experience with what they already know. Updates to the Movies & TV app and Skype Preview app will take advantage of compact overlay windows in the near future!

Introducing Dynamic Lock: Dynamic Lock automatically locks your Windows 10 PC when you’re not around based the proximity of a Bluetooth-paired phone. If your Bluetooth-paired phone is not found near your PC, Windows turns off the screen and locks the PC after 30 seconds. To enable Dynamic Lock, make sure your phone is paired to your PC via Bluetooth and go to Settings > Accounts > Sign-in options and toggle Dynamic lock to “on”.

NOTE: See known issues below regarding a bug preventing PCs on this build from successfully pairing devices via Bluetooth.  

New Share icon: We’re introducing a new share icon. Apps that used the “share” font glyph in Segoe MDL2 assets should get the change automatically. You can read more about the change here.

Windows Game Bar improved full-screen support: We got a ton of feedback on Game Bar and we are continually adding more titles with this support. In this build, we’ve added support for 52 additional games in full-screen mode with Windows game bar. As always, just hit WIN + G to invoke Game Bar to capture a recording or screenshot.

Other changes, improvements, and fixes for PC

• We fixed the issue causing Tencent apps and games to crash or work incorrectly.
• We’ve updated OOBE so that if there’s no detected audio output device, for example with VMs, it now skips Cortana’s introduction.
• [GAMING] We fixed the issue causing popular games may experience crashes or black screens when trying to load due to a platform issue.
• [GAMING] We fixed the issue where Game Mode is enabled system wide by default, however, the ON/OFF toggle in Settings will incorrectly show it as being OFF until the user manually toggles the Setting to ON which will cause it to update and accurately display the status of Game Mode system wide.
• We fixed an issue where the night light quick action was unexpectedly disabled in the last Insider flight.
• We fixed an issue resulting in audio going quiet each time the Start menu is opened after a SpeechRuntime.exe crash.
• Dragging apps from the all apps list to pin on Start’s tile grid will now work. We also fixed an issue on recent builds where some tiles might unexpectedly appear blank and with a name starting with “P~…” after upgrading.
• We fixed an issue where Win + Shift + S wouldn’t work to capture a region of the screen if the Snipping Tool was already running. We also fixed an issue where taking a snip with the Snipping Tool would fail on 4k monitors when 60-80% was selected.
• We fixed an issue resulting in “Fn”+”Pause/Break” key not working to pause the checking progress when running chkdsk.
• We fixed an issue where resizing windows with a pen would be unexpectedly slow. We also fixed an issue where resizing a window across monitors with different DPIs could be unpredictable.
• We fixed an issue where the Windows Ink highlight preview wouldn’t be visible in Web Notes when Microsoft Edge was using dark theme.
• We’ve improved gesture recognition for 3 finger swipes on precision touchpads.
• We fixed an issue where a number of files with the name GLOB(0xXXXXXX) could be unexpectedly found in the system root directory after upgrading.
• We fixed an issue where you couldn’t rename disk volumes via File Explorer in recent flights.
• We fixed an issue where rapidly tapping a button to bring up the new Share experience, for example in Microsoft Edge, could result in the Share UI not coming up again until the device had been rebooted.
• We fixed an issue resulting the lists of thumbnails in Photos and Groove Music visibly shifting up when the app resumed.
• We fixed an issue where the Themes Settings page would blink when a theme was deleted.
• We’ve updated the help string on each page of Settings to be a bit more succinct.
• We fixed an issue resulting in not being able to type ę on the Polish keyboard into the Settings search box.
• We fixed an issue where Cortana Background Task Host might have ended up using an unexpectedly large amount of CPU in recent flights. We also shorted the two factor authentication notification from Cortana so that it won’t be truncated.
• We fixed an issue where the UI to input credentials wouldn’t have keyboard focus after initiating a remote connection to another PC.
• We’ve improved reliability when handling malformed Gifs in XAML-based apps.
• The icons should now be shown as expected instead of squares under Settings > Gaming.

Known issues for PC

• [UPDATED] IMPORTANT: You may see “Initializing…” when attempting to download this build and the download progress indicator shown when downloading this build may seem broken under Settings > Update & security > Windows Update. It may look like you’re getting stuck at 0% or at other percentages. Ignore the indicator and be patient. The build should download fine, and the installation should kick off. See this forum post for more details.
• While we fixed the primary bug causing this issue, some Windows Insiders may still hit nonstop exceptions in the Spectrum.exe service causing their PC to lose audio, disk I/O usage to become very high, and apps like Microsoft Edge to become unresponsive when doing certain actions such as opening Settings. As a workaround to get out of this state, STOP the Spectrum.exe service and delete C:\ProgramData\Microsoft\Spectrum\PersistedSpatialAnchors and reboot. For more details, see this forum post.
• Going to Settings > Devices will crash the Settings app. You will be unable to pair a Bluetooth device. Bluetooth quick actions from Action Center also does not work.

• Microsoft Edge’s “Inspect Element” and “View Source” options don’t correctly launch to the DOM Explorer and Debugger, respectively.
• Under Settings > Update & security > Windows Update you might see the text “Some Settings are managed by your organization” even though your PC isn’t being managed by an organization. This is a bug caused by an updated flight configuration setting for Insider Preview builds and does not mean your PC is being managed by anyone.
• On some PCs, audio stops working sporadically with ‘device in use’ error”. We are investigating. Restarting the audio service may fix things for a bit.
• The Action Center may sometimes appear blank and transparent without color. If you encounter this, try moving the taskbar to a different location on screen.
• The icon for Windows Insider Program under Settings > Update & security is shown as a square.

Last week Microsoft release yet another update for the Fast Ring Insiders, Build 15019 containing the Game mode update, this build is running smoothly on my devices, if you haven’t do it yep upgrade your systems.

Caution for those who play al lot of games, they might show some issues.

Today we are excited to be releasing Windows 10 Insider Preview Build 15019 for PC to Windows Insiders in the Fast ring. FYI: This build does have some platform related bugs that will impact the ability to play popular games on your PC. These platform bugs are unrelated to the new gaming features such as Game Mode. We recognize that this is painful for those wanting to try out the new gaming features announced this week. We deliberated a lot on whether to release this build to Insiders with these issues, however we decided to go ahead and release it as we need feedback from Insiders on other areas of the OS. The team is working hard to get these platform bugs fixed and we plan to push the new gaming features again when we release a build that includes these fixes.

What’s new in Build 15019

Xbox Gaming Features: As part of Windows and Xbox Insider Programs, updates have rolled out this week bringing some awesome new features for gamers. For more details – check out this blog post on Xbox Wire.

• Built-in Beam streaming: Beam is the easiest and quickest way to stream gameplay, and it’s part of Insider Preview builds starting today for both your Windows 10 PC and Xbox One. After updating to this build, you can start Beam broadcasts by pulling up the Game bar — Windows + G.

• New Games section in Settings: A new settings page has been added to Windows 10’s Settings app specifically for gaming: Gaming. This new section will be identifiable with the Xbox logo. We’re also beginning to consolidate some system and user settings for gaming in this unified location, where PC users are accustomed to accessing their settings. Starting today, you’ll find settings for Game bar, GameDVR, Game Mode, and broadcasting and streaming in this new Gaming area. Not all elements of this section will be visible in today’s Windows Insider build, but we’ll continue to develop and deploy Gaming settings over time.

• Game Mode: With Game Mode, it’s our goal to make Windows 10 the best Windows ever for gaming. Our vision is that Game Mode optimizes your Windows 10 PC for an improvement in game performance. To enable Game Mode, go to Settings > Gaming > Game Mode toggle the feature on. Doing this will give you the ability to enable the feature for each UWP and Win32 title you play by pulling up the Game bar (Windows + G) and the clicking the Settings button. There you’ll be able to opt individual games into using Game Mode. (See below for an known issue regarding Game Mode in this build.)

We look forward to your feedback! We’ll test and refine these features between now and release and continue to evolve the Windows 10 gaming experience.

Windows Game bar improved full-screen support: We are continually adding more titles with this support. In this build, we’ve added support for 17 additional games in full-screen mode with Windows Game bar. As always, just hit WIN + G to invoke Game bar to capture a recording or screenshot.

• Battlefield 3
• Call of Duty: Black Ops 2
• Call of Duty: Black Ops 2 – Zombies
• FIFA 14
• FIFA 17
• FIFA Manager 14
• Grim Dawn
• Guild Wars 2
• Left 4 Dead 2
• MapleStory
• Paragon
• Payday 2
• Rocket League
• The Elder Scrolls Online
• The Sims 4
• Tom Clancy’s Rainbow Six Siege
• Warface

Tip: You can control this feature through the Windows Game bar settings. In the settings dialog, look for the “Show Game bar when I play full-screen games” checkbox. See Major Nelson’s post on Game bar for more info on how to adjust settings for best game performance.

Microsoft Edge can now read aloud: Last week many of you asked about this and we are proud to announce that Microsoft Edge will now read aloud* your e-books! Just press the “read aloud” button at the top-right corner after opening one of your e-books and listen to Microsoft Edge read you the book with focus on the line and the word being read along. This feature is also extended to all non-store EPUB files opened using Microsoft Edge.

*Supported languages: ar-EG, ca-ES, da-DK, de-DE, en-AU, en-CA, en-GB, en-IN, en-US, es-ES, es-MX, fi-FI, fr-CA, fr-FR, it-IT, ja-JP, nb-NO, nl-BE, nl-NL, pt-BR, pt-PT, sv-SE, tr-TR, zh-CN.

Microsoft Edge and emoji: Microsoft Edge will now display full-color, updated emoji by default on websites that use emoji.

Continuing our progress towards a more inclusive OOBE: You all gave us a TON of feedback on the new first experience over the past few weeks. The Windows Out-Of-Box-Experience (OOBE) Team offers their thanks and continues their work to reimagine how people set up their PCs for the first time. Building off what was first introduced in Build 15002, this build brings even more improvements to make setting up a PC more inclusive!

• Privacy: The new privacy settings in the set up experience (OOBE) that Terry talked about in this blog post are now included in this build.

• Wi-Fi Captive Portal: The Wi-Fi connectivity experience in OOBE has been updated to support “captive portal” Wi-Fi networks.  When connecting to such a Wi-Fi hotspot, OOBE will navigate to a lightweight browser experience allowing you to complete the connection and reach the internet.  We’ve also included some updates allowing you to configure some basic properties for the Wi-Fi network during OOBE.
• MSA Sign-in/Sign-up: The Microsoft Account (MSA) Sign-in and Sign-up flows in OOBE are now updated to the new design for the Windows 10 Creators Update. Users will see that these experiences are paginated and simplified will help in reducing the overall cognitive load and in improving accessibility in the MSA sign-in/sign-up experiences.

• Windows Hello enrollment: Users can now enroll into Windows Hello using the new design implementation for the Windows 10 Creators Update with Cortana voiceover and support for speech input.
• Updated voice: The audio track in this build is recorded by voice actors, so it is much friendlier and the intonations are better too (compared to the synthetic voice track we had in Build 15002).
• Subtitles: The primary purpose behind this redesign of OOBE is to be inclusive and improve accessibility. This build supports subtitles to ensure that our deaf/hard of hearing users are also included in the new Cortana voiced OOBE.
• Bug fixes and visual polish: This build also has improvements for visual polish and a good number of bug fixes which help in overall stability.

Insiders will still see that some pages (e.g. Enterprise flows and Ownership Disambiguation page) are in the design see in the Windows 10 Anniversary Update. This is a temporary state while we are working to convert these pages also into the new format.

Blue light is now night light: To make it more accurately reflect what the feature does, we’ve renamed it “night light”. We made some improvements to the night light feature that lets you preview the setting before applying it.

We also made some improvements in the range of color temperatures in the night light feature and fixed a few issues including:

• We fixed an issue where right-clicking the night light quick action from the Action Center and selecting Settings brought up the Settings home page and not the night light specific setting.
• We fixed an issue where waking your device from sleep or connecting a new monitor would not have the night light setting applied correctly.
• We fixed an issue where explorer might hang after waking a device if night light was enabled.

Night light still in the same place, so if you haven’t tried it out yet – you can do so via Settings > System > Display.

Resize your Virtual Machine Connection in Hyper-V: You can now quickly resize VMConnect by dragging the corners of the window and the guest operating system will automatically adjust to the new resolution. This requires that you are logged into the guest operating system and running in Enhanced session mode.

Store app and game download progress in Action Center: Building off of the work we shared with Build 15007, newly downloaded apps and games from the Store will now show download progress inside of the Action Center! Perfect for checking the status of a large game download while doing something else.

Improved discovery for Troubleshooters: Troubleshooters can find and fix many common problems for you. With Build 15019, we bring the latest piece of our ongoing effort to converge Control Panel into Settings and are happy to let you know that the Troubleshooters section of Control Panel has been migrated into Settings. We also flattened the hierarchy to make them easier to find, and added more solutions, too!  Head to Settings > Update & security > Troubleshoot to see the complete list. 

Improved high-DPI support for ITPros: With Build 15002, we shared our new option to override a GDI-based app’s high DPI scaling with our own System (Enhanced) scaling. With Build 15019, we’re happy to let you know that this System (Enhanced) application compatibility setting will now also available to be enabled or disabled via the Windows ADK for IT Professionals, so you can make adjustments to a broad audience of PCs.

Known issues for PC

• IMPORTANT: The download progress indicator shown when downloading this build is currently broken under Settings > Update & security > Windows Update. It may look like you’re getting stuck at 0% or at other percentages. Ignore the indicator and be patient. The build should download fine and the installation should kick off. See this forum post for more details.
• After updating to this build, nonstop exceptions in the Spectrum.exe service may occur causing PCs to lose audio, disk I/O usage to become very high, and apps like Microsoft Edge to become unresponsive when doing certain actions such as opening Settings. As a workaround to get out of this state, you can delete C:\ProgramData\Microsoft\Spectrum\PersistedSpatialAnchors and reboot. For more details, see this forum post.
• Some Windows Insiders may have had trouble connecting to certain Google sites due to an implementation of a new security model being rolled out to further enhance user security. The team is working on a resolution. In the meantime, users can access these sites from an InPrivate tab.
• Extensions in Microsoft Edge do not work in this build. Extensions may appear to load but will not function as expected. This issue should be fixed in the next Insider release build we release. If you depend on extensions in Microsoft Edge, we recommend skipping this build. You can pause Insider Preview builds by going to Settings > Updates & security > Windows Insider Program, clicking on “Stop Insider Preview builds”, and choosing “Pause updates for a bit”.
• Microsoft Edge F12 tools may intermittently crash, hang, and fail to accept inputs.
• Microsoft Edge’s “Inspect Element” and “View Source” options don’t correctly launch to the DOM Explorer and Debugger, respectively.
• Windows Insiders will unexpectedly see a “Mixed Reality” entry on the main page of Settings.
• Some captive portal Wi-Fi networks may fail to connect during OOBE. If a captive portal network is using DNS hijacking to redirect to a secure site, the captive portal app will crash and the user cannot clear the portal.
• Yes/No voice commands in the Wi-Fi portion of OOBE are currently failing.
• Quicken 2016 will fail to run with an error stating .NET 4.6.1 is not installed. For Insiders familiar with Registry Editor, there is an optional workaround. Take ownership of the following registry keys and edit the “version” value to be 4.6.XXXXX instead of 4.7.XXXXX:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\NET Framework Setup\NDP\v4\Client

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\NET Framework Setup\NDP\v4\Full

Note: Please take caution when editing the registry. Changing the wrong value can have unexpected and undesirable results.

• Dragging apps from the all apps list to pin on Start’s tile grid won’t work. For now, please right-click on the desired app in order to pin it.
• Some Tencent apps and games may crash or work incorrectly on this build.
• Under Settings > Update & security > Windows Update you might see the text “Some Settings are managed by your organization” even though your PC isn’t being managed by an organization. This is a bug caused by an updated flight configuration setting for Insider Preview builds and does not mean your PC is being managed by anyone.
• On some PCs, audio stops working sporadically with ‘device in use’ error”. We are investigating. Restarting the audio service may fix things for a bit.
• The Action Center may sometimes appear blank and transparent without color. If you encounter this, try moving the taskbar to a different location on screen.
• ADDED: For the update to Build 15019, there have been two issues surrounding Windows Update that have arise: 1.) You may see an error such as 0xC1900401, or a note that the build is not yet available for your device 2.) Your PC scans and finds Build 15019, but it appears to hang on “Initializing…” and doesn’t appear to begin downloading the build. See this forum post.

Gaming known issues

• Popular games may experience crashes or black screens when trying to load due to a platform issue.
• When clicking on certain elements in desktop (Win32) games, the game minimizes and cannot be restored.
• Game Mode is enabled system wide by default, however, the ON/OFF toggle in Settings will incorrectly show it as being OFF until the user manually toggles the Setting to ON which will cause it to update and accurately display the status of Game Mode system wide.
• Broadcasting to Beam via the Game bar currently requires a number of Privacy settings to be changed. Please visit this forum post.
• Certain hardware configurations may cause the broadcast live review window in the Game bar to flash Green while you are Broadcasting. This does not affect the quality of your broadcast and is only visible to the Broadcaster.
