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!
