Today Microsoft released Windows 10 Insider Preview Build 17686 (Redstone 5) to insiders in the fast and skip ahead rings. This build adds local experience, privacy, and Windows Mixed Reality improvements.
Improved Local Experience
This build adds a new "Region" settings page that allows you to override various settings related to your default Region settings. For example, you can change the type of calendar you wish to use, which day is the first day of the week, and short date formats.
A new "Language" settings page has been added that allows you to download "Local Experience Packs", which add new languages, from the Microsoft Store. When installing multiple languages, you can change the order they are displayed and the first one will be used for the text in navigation, menus, messages, settings, and help topics.
You can access this new Language screen by going to Settings –> Time & Language –> Language.
If you have blocked access to your microphone in the settings, when you launch an App that wants to use it, Windows will display an alert asking you to review your privacy settings.
Windows Mixed Reality Improvements
You can now run Windows Mixed Reality without a monitor hooked up. You will still need a screen when setting up WMR for the first time, but you can configure it to automatically log you in, so you will no longer need it after.
This build also includes improvements to video capture in WMR as well as apps now having the ability to use the Camera Capture UI API to capture images of the mixed reality world.
To see the entire release notes, you can read the this blog post. Below are the latest fixes and changes in build 17686:
General changes, improvements, and fixes for PC
We fixed an issue resulting in frequent bugchecks on the previous build with CRITICAL_PROCESS_DIED error.
Settings > Gaming > Game DVR has been renamed “Captures”.
We fixed an issue where Paint and WordPad settings and recent files weren’t migrated during upgrades.
While we still have some work to do, you’ll find that when you update to this build, File Explorer will look a lot more complete in dark theme.
We fixed an issue resulting in the “Replace or skip files” dialog having some unexpected dark elements in recent flights.
We fixed an issue where the Japanese IME’s big mode indicator would appear in the center of the screen when bringing up UAC even if the mode indicator had been disabled in Settings.
We fixed an issue where the taskbar flyouts (network, volume, etc) didn’t have a shadow.
We fixed an issue where clicking on the plus button in the Clock and Calendar flyout from the taskbar didn’t do anything in recent flights.
We fixed an issue resulting in Command Prompt’s cursor appearing invisible in the last few flights.
We fixed an issue resulting in a high number of reliability issues when switching to the Microsoft Pinyin IME in recent flights.
We fixed an issue where the Emoji Panel might not dismiss if you clicked somewhere else on the screen.
After update, Mixed Reality Portal will reinstall the Mixed Reality Software and environment settings will not be preserved. If you need your Mixed Reality home experience to persist, we recommend skipping this build until these issues are fixed.
Some Insiders may find increased reliability and performance issues when launching Start on this build. We’re investigating.
Fonts acquired from Microsoft Store may not work in some apps.
When you upgrade to this build you’ll find that the taskbar flyouts (network, volume, etc) no longer have an acrylic background.
There is a bug in this build (and in Build 17682) that will impact driver testing scenarios. When executing HLK Component/Device driver tests, you may experience a bug check that blocks test execution. We are aware of the issue and actively working on a fix.
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. There has not yet been a RS5 build released to the Slow ring.
Known issues for Sets & Office
Sets UX for Office Win32 desktop apps is not final. The experience will be refined over time based on feedback.
The top of some Win32 desktop app windows may appear slightly underneath the tab bar when created maximized. To work around the issue, restore and re-maximize the window.
Closing one tab may sometimes minimize the entire set.
Tiling and cascading windows, including features like “View Side by Side” in Word, will not work for inactive tabs.
The Office Visual Basic Editor window will currently be tabbed but is not intended to be in the future.
Opening an Office document while the same app has an existing document open may cause an unintended switch to the last active document. This will also happen when closing a sheet in Excel while other sheets remain open.
Local files or non-Microsoft cloud files will not be automatically restored, and no error message will be provided to alert the user to that fact.
