What’s new Windows 10 Preview Build 18277
Here are all the new features, improvements and other changes included on Windows 10 19H1 Build 18277. You can read the full release note here from Microsoft blog.
Evolving Focus Assist
Focus Assist feature introduced in the Windows 10 April update, a bit similar to the DND feature on the phone. Once enabled this feature, it can be uninterrupted by social media or other notifications, and users can choose to automatically turn this feature on for a specific period of time.
And now with Todays Preview build 18277 the newly added feature allows users to be immune to these notifications in full screen mode. For example, when a user watches a movie, learns, and creates an Office document in full screen, the user will not be notified when the option is enabled so that the user can keep the notification quiet before exiting the full screen mode.
To enable this option, you would need to go to Settings > System > Focus Assist > Customize Priority List and check the box.
Action Center Improvements
The brightness adjustment in the new Action Center has been changed from button to slider. Microsoft said
“One of the most popular requests it gets for Action Center is to make the Brightness “quick action” a slider instead of a button. Now it is. “
In addition, the company also made it easier to manage Quick Action directly from the Action Center without having to go into the settings app. This means that users can more quickly arrange on the current page.
New Emoji coming in 19H1
Emoji 12 is also coming to Windows 10, and Microsoft says it’s currently working on implementing a refined back for 19H1 users.
The company says: “The complete list of emoji for the Emoji 12 release is still in Beta, so Insiders may notice a few changes over the coming flights as the emoji are finalized. We have a bit more work to do, including adding search keywords for the new emoji, and adding a few emoji that aren’t finished yet.
High DPI Improvements
From past few years, Microsoft has significantly improved the support of High DPI displays for Win32 applications. And Windows 10 19H1 will enable the new settings by default, automatically resolving the scaling issue, reducing the number of times users see the “Fix Blur App” notification.
Windows Security gets additional Windows Defender Application Guard settings
Insider can notice new options in quarantine browsing, allowing users to use the Application Guard to access the camera and microphone for control of the Edge browser. To turn this feature on in Application Edge for Microsoft Edge, you must have the camera and microphone settings turned on for your device in Settings > Privacy > Microphones and Settings > Privacy > Camera.
