Finally, Microsoft is adding visual improvements and bug fixes to the Out-Of-Box-Experience.

Action Center

Windows 10 build 15019 doesn't deliver significant changes to the Start menu and Cortana, but Action Center now displays apps and games download progress, which is very convenient to check the status of a large download while doing something else.


The Settings app in this release adds a slew of new features and improvements, including a new Gaming section identified with the Xbox logo with settings to configure Game bar, Game DVR, Broadcasting, and Game Mode. The Holographic section has now been renamed to "Mixed Reality" with options to configure Audio and speech, Environment, Spaces, and you can go to Uninstall to remove or troubleshoot the experience.

In previous builds, Microsoft introduced a new feature called "Blue Light," which allows you to control the blue light that your screen emits to help you reduce eye strain and improve sleep quality. In this new version of Windows 10, they've renamed the feature "Night Light".

In addition, the feature now lets you preview the settings before applying it, and there are a few improvements in the range of color temperatures and bug fixes.

On Settings > Gaming, the new Game bar page lets you configure settings to control various aspects of the feature.

The Game bar page includes options to enable game recording, screenshots, and broadcast using the bar.

You can allow the Game bar to open using a button on your controller, and decide whether to show the Game bar when playing games in full-screen mode.

The page offers settings to configure audio quality, whether to use your webcam while broadcasting, and there is an option to prevent the mouse cursor from appearing in broadcasts.

Game Mode

On Settings > Gaming, the new Game Mode page includes a couple of settings to allow Windows 10 to use Game Mode.

Game Mode is a feature debuting on build 15019 that aims to optimize your computer performance by prioritizing CPU and GPU resources for an improved gaming experience.

To use Game Mode on Windows 10, you must turn on the Use Game Mode toggle switch on this page. Then when you're playing a game, use the Windows key + G keyboard shortcut, click the Settings button, and make sure to check the Use Game Mode for this game option.

Additionally, the settings page includes an option to get Game Mode notifications.

Feedback & diagnostics

On Settings > Privacy, the Feedback & diagnostics page removes the drop-down menu, and you can now only belong to the Basic or Full group for feedback and diagnostics.

The page also adds a new option to let Microsoft provide more tailored experiences with relevant tips and recommendations using diagnostic data.

Windows Update

On Settings > Update & security, the Windows Update page remains intact, but in the Restart options, you now have an option to show notifications to get reminded when your computer will restart to apply a new update.


On Settings > Update & security, the Troubleshoot page is a new place you can go to troubleshoot and fix common Windows 10 problems.

These troubleshooters are nothing new as they were part of the Control Panel, but now Microsoft is migrating them to the Settings app.

The new page offers the following troubleshooters:

  • Internet connections
  • Playing Audio
  • Printer
  • Windows Update
  • Blue Screen

  • Search and Indexing
  • Shared Folders
  • Speech
  • Video Playback
  • Windows Store Apps

When you have a problem on Windows 10, you can come to this page and run one of the troubleshooters to quickly fix the issue.

This page still under development, and even though, you'll no longer find them in Control Panel, running a troubleshooter will launch the same Control Panel experience.

Audio and speech

On Settings > Mixed Reality, the Audio and speech page now adds options to configure the speakers and microphone to use while in mixed reality mode.

Under Speech, there is an option to enable speech recognition while in mixed reality.


On Settings > Mixed Reality, the new Environment page adds an option to clear the environment data that Windows 10 collects to give you the best mixed reality experience.

According to the description, removing the data, some apps content may disappear from your environment, and you won't be able to see the boundary you set up. However, you can always open the Mixed Reality Portal on the Start menu to set up the boundary again.

Headset display

On Settings > Mixed Reality, the new Headset display page is where you'll go to adjust your headset's visual settings.

The page offers a drop-down menu to change the visual quality to High or Standard. And under Calibration, you can set a custom value to improve the quality of your visuals.

Note that Microsoft also included a Default button to go back to the predefined settings.


On Settings > Mixed Reality, the new Spaces page is specific to control HoloLens settings.

If you're not seeing holograms or you're seeing the incorrect ones, you can click the Remove nearby holograms button to fix the problem.

If you're constantly having problems with holograms you've placed, you can click the Remove all holograms button to start over recreating your holograms.


On Settings > Mixed Reality, the new Uninstall page allows you to uninstall Mixed Reality if you're having issues, or you simply don't use it, and you want to free up some space on your computer.

Removing the feature is as easy as clicking the Uninstall button, but the Mixed Reality apps will remain on your computer. However, you can always uninstall the apps by using right-click and selecting Uninstall from the Start menu.

The page also features some instructions to reinstall Mixed Reality on your computer.

Microsoft Edge

Windows 10 build 15019 also delivers a new update for Microsoft Edge that bumps the version number to 40.15019 and brings a few new features.

Microsoft Edge recently introduced a new feature to read books you purchase from the Windows Store, and in this new version, when you're reading a book, you'll find a new button in the top-right corner that allows the browser to read the ebook aloud.

When clicking the "Read aloud" button, you can also access the controls to change reading speeds, pause, and jump to previous and next paragraphs.

This new feature works with Windows Store ebooks as well as with unprotected epub files you open with Microsoft Edge.

The ebook viewer has also been updated to let you use the Ctrl + Mouse wheel to zoom an image.

Finally, this new version of the browser renders emojis on websites in full color by default.

Additional changes

On build 15019, Windows Defender Security Center now shows a new App & browser control entry, but the page isn't working.

Hyper-V gets updated, and now you can quickly resize VMConnect by dragging the corners of the window, and the guest operating system will automatically adjust to the new resolution.

Based on feedback Microsoft changed the look of the Virtual Touchpad to make the left/right buttons more visible.

In addition, this flight renames "Windows Holographic" to "Mixed Reality Portal".

Wrapping things up

Windows 10 build 15019 is a big update that delivers a bunch of new features, improvements, and fixes, especially for gamers and even for users with mixed reality headsets. However, this particular update ships with a number of bugs and things not working correctly.

As with any pre-release version of Windows 10, it's not recommended to install this build on your main computer to avoid potential problems.

  • Microsoft is so bad with naming. Again do they do a odd rename and instead of sticking with MS Holographic they do a generic Mixed Reality out of it. *narf*
  • I can understand what you mean. Microsoft usually does a pretty good job with naming but I liked Microsoft Holographic.
  • Usually does a good job with naming? Haha, since when?
  • Since Xbox ONE (360->1)... or since Windows 10 (Windows 9) or since Windows Mobile -> WindowsPhone -> Windows 10 for Mobile
  • Windows 9 was Windows 8.1
  • Windows 8.1 was basically Windows 9. They used a different product key method and everything if I remember right... 
  • I heard it was going to be called Zune Vision..
  • Also, I believe Holographic is a TM name of their Mixed Reality device.  Calling all the features by "Mixed Reality" allows their partners to also create devices without confusion.  Would be like if they had a settings section actually called "Band settings" when "Band" is their device, it would actually "Wearable settings" when it controls all the 3rd party devices too.  Get what I'm saying? Leaves things open for changes later now.
  • Had to rollback, all my edge extensions broke. And action center is a total mess, a clear overlay
  • That's fast ring for you.
  • If you read the blog post like you were supposed to, its says Edge extentions don't work on this build.
  • Both those issues were described in the initial blog post, if you had bothered reading it. All Edge extensions will fail to work, and if you're having issues with the Action Center try moving the Task Bar to a different location on the screen.
  • To be fair they did say that if you value your extensions in edge this is not the preview for you and provided instructions on how to skip.
  • Same problem here
    Action centre not seen
  • Try moving the Taskbar to a different location on your screen and try again.
  • Restart Windows Explorer to get Action Centre back.
  • Still can't install on SP4. GSOD at 95% then reverts back to previous version.
  • Same here.
  • Did you remove your sd card before upgrading?
  • Anyone know where we get a hand on that wallpaper? :0
  • Would like to know that as well
  • The car one? That's Forza running in the background for game mode. It's the game running and not a wallpaper. edit: Oh, maybe you meant the one from the video that I hadn't watched. I wasn't able to find it.
  • I'm not a Windows Insider but I hope by the time Creators update is released these are fixed: -OneDrive placeholders!!!
    -Damn Edge bugs, particularly on the SP4 it has been happening for months, sometimes Edge needs to be killed in task manager because the X won't close quit it, and very often opening a new window in private mode hogs the CPU (and there goes the much boasted battery saving...)
    -Allow to search task view by window title or something, I don't want to take a look at dozens of previews just to find the right window.
    -Add a app wishlist to the Windows Store like Google Play.
    -Seamless sync of system settings, installed apps, app settings and start screen tiles between devices.
    -Add a quick action to the notification center to inhibit lockscreen.
    -Oh, and if Microsoft is intending to make us wait decades to roll out Cortana globally, at least let us be able to use it in English without messing around with regional settings! Not necessarily about Windows but also it would be nice if: -The whole mess with contacts between Skype, People app and Outlook was fixed, it's stupidly annoying, like when I want to send a email to a contact I have in People app but it won't appear on Outlook desktop. Sadly it seems People Hub has been delayed and as of right now, Skype contacts are all butchered.
    -OneNote crawling sync speeds were improved.
  • So far: No OneDrive placeholders, still a LOT of bugs in Edge (it's still slow as heck, often just freezing at the E splash page), no appreciable changes in Skype/People/Outlook and, in fact, Skype is still just as lame in features as it's every been, particularly if you're trying to use it as your default SMS client (can't delete conversations, attaching documents is painful or non-existent), sync of settings is NOT nearly thorough enough and is not consistent between my devices. I don't know what you're asking for regarding the task view. I don't have a need for an app wishlist--especially if it's something Google uses.  I don't use the notification center and would completely remove it if I was able to.
  • The Edge part happens in RS1 as well
  • Awesome, I can uninstall Mixed Reality altogether!  Nice!
  • I'd like Edge to behave as it should and be more stable and less glitchy. v13 and 14 improved this, but we are over 1 after v12 launch and this is still happening
  • How safe is it to install this build, since itæs close to general release? I was an Insider for TH1, 2 and RS1, but not many features appealed to me now to go all-in... Oh, and under safe, I mean stable.
  • To be honest this one breaks as many things as it introduces so I would suggest because you are asking this is not the preview for you.
  • Thanks
  • Solitaire seems to have had a major downgrade after updating to 15019. Events have disappeared completely and the end-game UI has reverted to the initial release version.
  • I am rolling back to the previous build. This one appears to have broken my USB audio capability. I have a Behringer Xenyx X1222USB mixer attached (it's been working for two years, no issues, until now) and use XSplit Broadcaster.  With this build XSplit either can receive audio from the board or send audio, but no longer at the same time.  When audio input works, anything that uses an audio channel in XSplit locks up.  A complete reboot usually gets audio input from the board working, but no media apps (Groove, Windows Media Player) will play.  Not good.
  • From Windbeta to WindowsCentral, always enjoy your detailed write-ups :)
  • Yet Windows explorer still does not fully support file paths longer than 255 characters in length.. still have to use Totalcommander for any type of deeply nested files/folders. Can't see hard drive S.M.A.R.T. data without third party software, nor laptop battery wear or voltage.
  • Awesome build!
  • Dota 2?
  • Wallpaper?
  • Please i know this off topic but can someone tell me how to download 250mb and above apps from the windows 10 mobile store without wifi. I do not have access to Wifi so i use my cellular data.
