Today, Microsoft  released Windows 10 Insider Preview Build 18267 (19H1) to Windows Insiders in the Fast ring.

What’s new in Build 18267

Input Improvements

Vietnamese Telex and Number key-based keyboards are now available on your PC: Do you write Vietnamese? With this build you can now use Vietnamese Telex and Number-key based (VNI) keyboards for typing Vietnamese.

Here’s a short gif of what it looks like (using the touch keyboard so you can see what Microsoft is typing):

If your native language is Vietnamese or you have some knowledge of the Vietnamese language,  here are the steps to get started:

1. Select Start > Settings > Time & Language > Language from the navigation menu.
2. Select the + icon labeled [Add a preferred language] (or skip to step 4 if Vietnamese was already added)
3. Type “Vietnamese” in the search box and select Vietnamese. Click Next button and install Vietnamese on your device, which will return you to Language page.
4. Click Vietnamese, and then click Option button. Which will navigate you to Language options: Vietnamese.
5. Select the + icon labeled [Add a keyboard] (or skip to step 7 if your target keyboard was already added)
6. Enable the Vietnamese Telex keyboard or Vietnamese Number key-based keyboard (whichever you prefer).
7. Click the input indicator button on the taskbar (or press Windows key + Space) and select Vietnamese Telex or Number-key based keyboard. Input anything via your hardware keyboard or touch keyboard.

More symbols are now available on the touch keyboard: Now you can easily access more symbols and special characters directly from touch keyboard. After changing to the number & symbols view (&123) on the touch keyboard, just tap the new ‘? ‘ key and you’ll now see a number of tabs with lists of symbols.

Accessibility Improvements

• Narrator works better with Chrome now! Using up and down arrows in scan mode, navigating with tab key, continuous reading commands, and navigating by headings and links have initial support for Chrome, with more functionality coming in future flights.
• Narrator Braille: BRLTTY version 5.6 is now provided which adds USB support for Inceptor and Orbit 20 displays. In addition, the BrailleNote Touch is recognized when using USB.  Liblouis binaries and tables have been updated to version 3.7.0.
• UI Automation framework IAccessible2 Support: The UI Automation framework now supports translating IAccessible2 information from Chrome, which supports IAccessible2 rather than UI Automation. This enables UI Automation clients to receive the IAccessible2 information through the UI Automation client

Enhanced Mode for Search Indexer

To improve our search indexing, Microsoft created a new feature that enables Windows to search all your folders and drives, instead of limiting search to your documents, pictures, videos, and desktop by default. To turn it on, search for Windows search settings, and in the Searching Windows settings, under “Find My Files”, select Enhanced to begin the one-time indexing process. It will take about 15 minutes for search to begin returning these additional files in results. If you have lots of files, it may take longer. Make sure you plug in before you start, indexing is a resource-intensive activity.

When the indexing is complete, you’ll be able to find all your files almost instantly when you use Windows Search. To exclude a folder from search, add it to the Excluded Folders list.

Known issues

• Task View fails to show the + button under New Desktop after creating 2 Virtual Desktops.
• Some users will notice the update status cycling between Getting Things Ready, Downloading, and Installing. This is often accompanied with error 0x8024200d caused by a failed express package download.
• If you change Task Manager settings, the next time Task Manager is opened it will revert to default.
• If you have a have a large number of OTF fonts, or OTF fonts that support the extended East Asian character set, you may experience some unexpectedly missing text across the system. Microsoft is working on a fix. If you encounter this issue, navigating to the Fonts folder (c:\windows\fonts) may resolve it.

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.

Windows 10 Insiders can download the update by Checking for Updates in Settings.
