Microsoft has released first Windows 10 Build 18204 (Redstone 6, codenamed 19H1) for those in the Skip Ahead ring. With a number of new features “Flashlight” feature for Mixed Reality uses Edge browser improvements, New set of emojis, Kiosk setup experience and more. As per Microsoft blog Windows 10 Build 18204 (19H1) continue from Redstone 5 builds and Both Windows 10 Build 17723 and 18204 contain the same features and improvements. Microsoft’s Dona Sarkar writes in a blog post
Going forward, RS5 builds will come from the RS5_RELEASE branch. For Insiders who chose to “skip ahead”, 19H1 builds will continue to come from the RS_PRERELEASE branch. Insiders can see the branch name in the watermark at the lower right of their desktop. Right now, the builds from these branches are largely the same which is why we’re only doing a single blog post for both of today’s new builds. However, in the future, we will be doing separate blog posts for each.
What’s new Windows 10 Build 18204?
Flashlight feature for Mixed Reality: Today we are excited to announce that we are adding the ability to peer into your physical environment through Flashlight – without removing your headset! With the latest Windows Insider Program build, you can open a portal into your real world at any time via the Start menu, a button shortcut, or a voice command. This opens a low-latency pass-through camera feed connected to your controller. It’s comfortable, intuitive, and keeps you immersed.
New Microsoft Edge Group Policies: The Microsoft Edge team introduced new Group Policies and MDM settings for IT administrators to manage Microsoft Edge. The new policies include enabling/disabling full-screen mode, printing, favorites bar, and saving history; prevent certificate error overrides; configuring the Home button and startup options; setting the New Tab page and Home button URL and managing extensions. Learn more about the new Microsoft Edge policies.
New set of Emojis: as of today they’re now available for Insiders to try in the build. Including superheroes, redheads, a softball, a pirate flag and a llama all made the cut. You can access them using the Emoji Panel (WIN+.) or the touch keyboard.
When you have the build of today, you will also discover that we have made some changes to some of our existing emojis: here are some examples:
Leap Second Support– Windows will now support these occasional 1-second adjustments in a traceable and UTC-compliant manner. What’s a leap second? As the earth’s rotation slows, UTC (an atomic timescale) diverges from mean solar time or astronomical time. Once UTC has diverged by at most .9 seconds, a Leap Second is inserted to keep UTC in-sync with mean solar time. Since the practice of inserting leap seconds began in 1972, a leap second has typically occurred every 18 months.
Precision Time Protocol– For the highest accuracy environments, you can now improve your time accuracy by leveraging a new time protocol that delivers far more accurate time samples to the endpoint (Windows Server 2019 or Windows 10, host or virtual machine).
Software Timestamping– You can now further improve your network time accuracy by eliminating the software delay introduced by the Windows networking stack.
We have introduced a simplified assigned access configuration page in Settings that allows device administrators to easily set up their PC as a kiosk or digital sign. This new page provides a wizard experience that walks you through the kiosk setup flow including creating a kiosk account that will automatically sign in on device start.
We are very excited to announce that Microsoft Edge now works with assigned access which allows IT administrators to create a tailored browsing experience designed for kiosk devices.
Have you ever had to stop what you were doing, or wait for your computer to boot up because the device updated at the wrong time? We heard you, and to alleviate this pain, if you have an update pending we’ve updated our reboot logic to use a new system that is more adaptive and proactive. We trained a predictive model that can accurately predict when the right time to restart the device is. Meaning, that we will not only check if you are currently using your device before we restart, but we will also try to predict if you had just left the device to grab a cup of coffee and return shortly after.
In RS5, we’re making it easier to access the Game bar. In this flight, you can now discover Game bar from the Start menu or bring up Game bar by using the Win + G shortcut at any time.
Along with these features, Microsoft especially focuses to patch the bugs ( “…” menu not working in multiple apps (including Microsoft Store, Photos, and Screen Sketch), CRITICAL PROCESS DIED bug check and more), which previously reported by users. Here the full list of what’s fixed and broken in Windows 10 Build 18204 (19H1) and Build 17723 (Redstone 5)
