Today Microsoft released Windows 10 Insider Preview Build 17723 (Redstone 5) to insiders in the fast ring and Redstone 6 19H1 Build 18204 to insiders in the skip ahead rings. This is the first Redstone 6 19H1 build released to insiders, but for the most part resolves the same bugs and adds the same features as the Redstone 5 build released today.

Both of these builds come with a new Mixed Reality Flashlight feature, improvements to Microsoft Edge, the introduction of Emoji 11, improvements to time functions, improvements to kiosk mode, and an improved update experience.

Mixed Reality Flashlight

Microsoft added a new tool called Mixed Reality Flashlight that allows you to peer into the real world using a camera attached to your controller. This allows you to quickly see whats happening in the real world without taking off your VR headset.

Microsoft Edge Improvements 

Microsoft created new group policies that allow you to control the behavior of 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.

XSS Filter has also been retired in favor of Content Security Policies.

Emoji 11

Unicode 11 comes with 157 emojis and this build allows you to try them out. You can access them using the Emoji Panel (WIN+.) or the touch keyboard.

 

Time Accuracy and Traceability improvements

This build includes updates to time related functions by:

  • 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.

For a full write up with more details about these new improvements, please see our announcement here.

Improved Kiosk Setup 

This update includes an improved Kiosk setup experience. According to the announcement:

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.

Improved Update Experience

In order to improve the update experience so that Windows does not reboot your computer while you are using it and then force you wait to wait for the install the update, Microsoft has been working on predictive models that detect the right time to install a Windows update. These models will not only detect if you are using the computer before restarting, but will also try to predict if you left your computer briefly and are expected to come back to it.

To see the entire release notes, you can read the this blog post. Below are the latest fixes and changes in build 17723 and build 18204:

General changes, improvements, and fixes for PC

  • We fixed an issue resulting in the “…” menu not working in multiple apps (including Microsoft Store, Photos, and Screen Sketch) where clicking on any of the items would just make the menu dismiss.
  • We fixed an issue where in certain cases on PCs with multiple monitors, all the windows might have appeared shifted “up” and mouse input going to the wrong location.
  • We fixed an issue where SNMP and the Windows Event Log service might start using an unexpectedly high amount of CPU in the last flight.
  • We fixed the issue with Windows Defender Application Guard no longer working after installing the Build 17713.1002 Cumulative Update.
  • We fixed an issue from the last flight where upon rebooting in order to start upgrading to the build, the system would boot back into the current build rather than the new one.
  • We fixed an issue resulting in upgrades to the previous build failing with error 0x8007001f.
  • We fixed an issue from the previous flight where Window Recovery Environment (WinRE) would not launch and resulted in “Reset this PC” and “Advanced startup” flows to be broken and appear to do nothing. We also fixed an issue from the flight before last (not visible in the last flight due to the aforementioned bug) where “Reset this PC” would initiate and rollback without completing the intended reset.
  • We fixed an issue resulting in some laptops experiencing a CRITICAL PROCESS DIED bug check when the PC was put to sleep by closing lid and the connected power disconnected.
  • We fixed an issue resulting in ShellExperienceHost.exe crashing when trying to pin apps to Start Menu via drag and drop.
  • We fixed an explorer.exe crash when launching the Default Apps Settings page via WIN+R ‘control /name Microsoft.DefaultPrograms /page pageFileAssoc’.
  • We fixed an issue where .mkv files were using a generic app icon in File Explorer instead of a thumbnail.
  • Delivery Optimization Settings now has a new icon.
  • We fixed an issue where suggestions on the main page of Settings would appear after a delay, making the Settings categories shift unexpectedly.
  • We fixed an issue where Notification Settings listed every possible quick action in the enable/disable quick actions section, even those not applicable to the PC being used (including two Focus Assist entries).
  • We fixed an issue where the systray overflow area could end up drawing slightly below the taskbar.
  • We fixed an issue resulting in the network state in the taskbar potentially becoming stale in recent builds (showing there was no connection when there was, and vice versa).
  • We fixed an issue where pinging PCs by name on the same LAN would do a case-sensitive name check.
  • We fixed an issue where using v6v4tunnel to establish a tunnel didn’t work.
  • We fixed an issue in Command Prompt from the previous flight where if a typed string wrapped around to a second line, you could only delete it up to the line break.
  • We fixed an issue resulting in Task View / Timeline crashing on launch for some Insiders in recent builds.
  • We fixed an issue where right-clicking an activity in Timeline was missing the “clear all from day” option.
  • When you open a PDF using Microsoft Edge, the activity will now be listed in Timeline.
  • We fixed an issue where sometimes you would see windows unexpectedly quickly reorder after exiting Task View without selecting a window.
  • We fixed an issue from recent builds where the clock in the taskbar was leaking graphics device context handles (HDCs) every time it redrew, leading to performance issues the longer a PC was running. Multiple factors can impact performance, so if you’re continuing to notice any issues after upgrading to this build, please log feedback including a performance trace with a short repro and description.
  • We fixed an issue resulting in not being able to distinguish the border between two overlapping Command Prompt windows.
  • We fixed an issue resulting in the tops of apps in tablet mode being clipped (i.e. missing pixels). Not fixed.
  • Thanks everyone for sharing your feedback about the new welcome screen string prompting you to lock your PC. For the time being we will be reverting this to the previous string “These updates will protect you in an online world”.
  • We’ve made some tweaks to the design of the Cortana & Search landing page, specifically in situations where Cortana isn’t enabled/supported.
  • We fixed an issue resulting in Microsoft Jigsaw hanging on launch in recent builds.
  • The settings menu in Microsoft Edge (“…”) is now acrylic.
  • When you right-click a book in the Microsoft Edge Books pane, you’ll now see an option to share the book.
  • We fixed an issue that could result in Microsoft Edge spellchecking even though spellchecking was turned off in Settings.
  • We fixed an issue where using the mouse wheel in Microsoft Edge would unexpectedly do a forward/back through browser history if focus was in the address bar and “Scroll inactive windows” was disabled.
  • We fixed an issue where when using certain sites to listen to music in Microsoft Edge, your mouse might experience a small freeze if moving when the song changed.
  • We fixed an issue resulting in apps like Adobe XD crashing on keypress in recent flights.
  • We fixed an issue that could result in a deadlock on certain devices after using the pen to ink.
  • We fixed an issue where the touch keyboard would still have a launch animation even if “Show animations” was turned off in Ease of Access Settings.
  • We fixed an issue where launching regedit.exe (or any .exe that requires elevation) from a non-elevated cmd window using the “start” start command produced a “parameter is incorrect” error.
  • We fixed an issue causing Narrator speech to fade when waking from sleep mode.
  • We fixed an issue where the error “Your fingerprint couldn’t be recognized. Try using a different finger.” was displaying unexpected characters in place of the apostrophe.

Known issues

  • The clock & calendar flyout may not appear until bringing up Start or Action Center (and then they will both appear at the same time). This same issue may also result in notifications not appearing until Start or Action Center is opened.
  • We’re progressing in our work on adding dark theme in File Explorer and the Common File Dialog – you’ll notice improvements in this build, although we still have a few things left to do. You may see some unexpectedly light colors in these surfaces when in dark mode and/or dark on dark text.
  • When you upgrade to this build you’ll find that the taskbar flyouts (network, volume, etc) no longer have an acrylic background.
  • When you use the Ease of Access Make Text bigger setting, you might see text clipping issues, or find that text is not increasing in size everywhere.
  • When you set up Microsoft Edge as your kiosk app and configure the start/new tab page URL from assigned access Settings, Microsoft Edge may not get launched with the configured URL. The fix for this issue should be included in the next flight.
  • On Build 17723 (but not Build 18204), you may see the notification count icon overlapping with the extension icon in the Microsoft Edge toolbar when an extension has unread notifications.
  • On Windows 10 in S Mode, launching Office in the Store may fail to launch with an error about a .dll not being designed to run on Windows. The error message is that a .dll “is either not designed to run on Windows or it contains an error. Try installing the program again…” Some people have been able to work around this by uninstalling and reinstalling Office from the Store. If that doesn’t work, you can try to install a version of Office not from the Store.
  • When the Narrator Quickstart launches, Scan Mode may not reliably be on by default. We recommend going through the Quickstart with Scan Mode on. To verify that Scan Mode is on, press Caps Lock + Space.
  • When using Scan mode you may experience multiple stops for a single control. An example of this is if you have an image that is also a link. This is something we are actively working on.
  • If the Narrator key is set to just Insert and you attempt to send a Narrator command from a braille display then these commands will not function. As long as the Caps Lock key is a part of the Narrator key mapping then braille functionality will work as designed.
  • There is a known issue in automatic dialog reading where the title of the dialog is being spoken more than once.
  • For more information about Narrator new keyboard layout and other known issues, please refer to (Intro to New Narrator Keyboard Layout doc).
  • ADDED: There is an issue where the tops of apps in tablet mode being clipped (i.e. missing pixels).

Known issues for Developers

  • If you install any of the recent builds from the Fast ring and switch to the Slow ring – optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.
