Another week, another Windows 10 19H1 Insider Preview build from Microsoft! This week, build 18277 is rolling out for Insiders in the Fast ring, featuring yet more minor changes and bug fixes for users to test and give feedback.

As a refresher, 19H1 is the next Windows 10 feature update scheduled for launch in April next year. So far, not much is known about what will be included in the update on desktop, outside of minor changes to the Windows Shell and under the hood improvements.

What's new in build 18277

Evolving Focus assist

Starting with the Windows 10 April 2018 Update, we embarked on a journey to help reduce the number of distractions you encounter when you're trying to get in the zone. With today's build, we're taking this to the next level: We've added a new focus assist option so that when you're doing anything full screen we can automatically turn on focus assist.

Improving your Action Center experience

One of the top requests we've heard from you is that you'd prefer the brightness quick action to be a slider instead of a button, and with today's build we're making it happen! You can now easily customize your quick actions right from the Action Center itself, rather than having to go into Settings. That means not only can you re-arrange in the moment, but you can also add any quick action you need on the fly, without needing for it to always take up space.

Preparing for Emoji 12

With today's build, Insiders will get a first look at the emoji we've designed so far in preparation for the Emoji 12 release! These emoji are available for use via the emoji panel (WIN + .) and the touch keyboard.

High DPI improvements

As many of you know, we've been working over the past few years to improve the High DPI story for Win32 apps on Windows. As part of this, some of you may recall getting a toast about fixing your apps that led you to this setting we added with Build 17063. In 19H1, we're enabling this setting by default, to help automatically address some of your scaling feedback, and reduce the number of times you see that "Fix blurry apps" notification.

And more!

As always, you can check out the Windows Blog for the complete changelog, including a list of known issues.

  • Wish they would add the ability to have multiple time rules for Focus mode, and be able to link it to a calendar or something (like android). I heard that windows phone 8 used to have that. I have my android phone synced to my class schedule so it never goes off in class. Don't know why windows doesn't have this, especially with Andromeda on the horizon. Still hoping.
  • Great idea.
  • Also, other ruled based Focus Assist features are a must-have if they ever plan to release mobile devices. Focus Assist should be able to react on GPS coordinates (fast travel means I am in a vehicle and should not be bugged), wifi connections (see that I am at home / in the office) and so on...
    I was hoping to see this coming to Microsoft Flow as well, unfortunately though it does not seem to be for thiese purposes.
  • Loving those new Action Center features, especially the ability to re-arrange on the fly.
  • What are they doing with that brightness slider... wasn't that supposed to go to the control center? Come on.
  • What control center? Isn't action center the control center?
  • That's supposed to come in some next version of win10, there are articles about it on WC.
  • Wonder how it will work with the on-the-fly rearrange functionality.
  • What chance do we have when no one knows what anything is known as?
  • Hopefully this will download and install cause the last build still hasn't finished downloading & installing on my laptop
  • ISO is available for the last build.
  • Settings/Cortana/Cortana across my devices, is empty... has no settings no nothing in it?
